Carrots. I just bought a five pound bag of carrots for three dollars. Roast them for like 40 min at 400 and they come out like sweet potatoes. Also potatoes are good. If you roast chickpeas with the carrots they turn into like peanuts.
Smart and final will have a 30 pound bag of carrots for like 12. How many pounds of carrots cna you eat a day? Put some hummus on them. Or like barbecue sauce and you are chillin.
