If the fridge is full of bits and pieces of veggies and fish meat, try making Bottom of the Fridge Stew. Begin by sauteing an onion in a little oil, add chopped cooked meat, chili, chicken, or other protein, stock to cover, salt, and pepper. Bring to a boil. Add 1/2 cup canned beans or cooked pasta, and broccoli, kale, or other greens (you can even add chopped leftover salad). Simmer 10 minutes and sprinkle with Parmesan cheese.
