According to the US Department of Agriculture, the average family of four wastes approximately $1,500 worth of food each year. When discarded food ends up in landfills, it generates methane, a potent greenhouse gas with nearly 100 times the warming potential of carbon dioxide. In California, nearly 6 million tons of food are thrown each year, and around 20% percent of all the material that goes to landfills is food scraps.
As individuals, we each have an important role in conserving resources and minimizing food waste. Initiatives like the Ugly Produce is Beautiful (UPIB) Educational Campaign aim to rescue nutritious fruits and vegetables from being discarded. Instead of simply disposing of surplus food, we should explore innovative approaches to handle it responsibly, including collaborating with organizations to distribute it or utilizing composting methods to enhance soil rejuvenation, and experimenting with new recipes that use food scraps and reduce waste.
With summer well underway, bringing with it a plethora of fresh fruits and vegetables in season, we thought it would be a good opportunity to share some recipes to reduce food waste.
Crunchy Veggie Chips
By using assorted vegetables and making good use of vegetable scraps, this recipe helps minimize food waste while providing a delicious and healthy snack option for summer. Enjoy them as is or serve them alongside your favorite dips or spreads.
Ingredients:
- Assorted vegetables (such as zucchini, carrots, sweet potatoes, beets, parsnips, and kale)
- Olive oil
- Salt
- Seasonings of your choice (such as paprika, garlic powder, chili powder, pepper or dried herbs)
Instructions:
- Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper or silicone mat.
- Wash and dry the vegetables thoroughly. Trim off any blemishes or tough parts. Save the vegetable scraps (peels, ends, and trimmings) for later use in stocks or compost.
- Slice the vegetables into thin, uniform rounds or strips. You can use a sharp knife, mandoline slicer, or a vegetable spiralizer, depending on the vegetable and the desired thickness.
- In a large bowl, toss the sliced vegetables with a drizzle of olive oil. Make sure the oil coats the vegetables evenly but isn’t excessive.
- Season the vegetables with salt and any additional seasonings you prefer. Be creative and experiment with different flavor profiles.
- Arrange the seasoned vegetable slices in a single layer on the prepared baking sheet, making sure they don’t overlap.
- Place the baking sheet in the preheated oven and bake for 15-25 minutes, depending on the thickness of the vegetable slices. Keep a close eye on them to prevent burning.
- After the first 10 minutes, flip the vegetable slices over for even browning. This step is optional but can help ensure crispy chips.
- Continue baking until the veggie chips turn golden brown and become crispy. Keep in mind that different vegetables may require different baking times.
- Remove the baking sheet from the oven and allow the chips to cool for a few minutes. They will become crispier as they cool down.
- Once cooled, transfer the veggie chips to a serving bowl or store them in an airtight container for later use.
Tips:
- Experiment with various vegetables and flavor combinations to discover your favorite combinations. Feel free to customize the seasoning to your taste preferences.
- Make sure to slice the vegetables into similar thicknesses to ensure even cooking.
- If you have vegetable scraps left, consider using them for homemade vegetable broth or composting to further reduce food waste.
- Store the veggie chips in an airtight container to maintain their crispiness.

Leftover Persian Tahdig (ته دیگ): When the “Bottom of the Pot” Is the Best Part
Literally translated, the Persian word tahdig (ته دیگ) means the “bottom of the pot”–but don’t let that fool you, it’s truly the best part! Before nonstick cookware, tahdig had to be scraped from the pot, resulting in crunchy rice kernels at the bottom.
Ingredients:
- 2 cups cooked basmati rice (leftover or freshly cooked)
- Leftover cooked vegetables or protein (such as chicken, beef, or fish)
- 1/4 cup vegetable oil or clarified butter (ghee)
- Salt, to taste
Instructions:
- Heat a non-stick frying pan or a pot over medium heat. Add the vegetable oil or clarified butter (ghee) and allow it to melt and heat up.
- If using leftover vegetables or protein, chop them into bite-sized pieces. Add them to the pan and sauté for a few minutes until they are heated through. If you don’t have any leftovers, you can skip this step.
- Spread the cooked rice evenly over the vegetables or protein in the pan, creating a flat layer. Press down gently to compact the rice.
- Reduce the heat to low and cover the pan with a lid. Allow the rice to cook undisturbed for about 30 minutes. This will create a crispy layer of tahdig at the bottom.
- After 30 minutes, remove the lid and check the bottom layer of the rice. It should have turned golden brown and crispy. If it needs more time to crisp up, you can cook it uncovered for an additional 5-10 minutes.
- Once the tahdig is crispy and golden, carefully loosen the edges of the rice with a spatula or a knife. Place a large serving plate upside down over the pan and quickly flip the pan to transfer the tahdig onto the plate. The crispy layer should now be on top.
- Season the tahdig with salt to taste. You can also sprinkle some additional spices or herbs if desired, such as cumin, paprika, or dried herbs like parsley or cilantro.
- Serve the tahdig as a side dish or main course, accompanied by your favorite sauce, yogurt, or salad. The tahdig can be enjoyed on its own or topped with additional cooked vegetables or protein if desired. Enjoy your delicious Persian tahdig with a crispy bottom layer–and the added satisfaction of minimizing food waste!
Note: Tahdig is traditionally made with plain rice, but incorporating leftovers can add extra flavor and reduce food waste. Feel free to experiment with different combinations of leftover ingredients and spices to create your own unique tahdig variation.
