Sauteed zucchini with fresh basil and oregano is lovely and fast. Zucchini is satisfying to grow because it produces so much in so little space. I also make zucchini casseroles and hash browns. You can grow everything you need for spaghetti sauce and salsa as well - tomatoes, sweet and hot peppers, onions, herbs, garlic.
Last summer I tried radish leaf soup. Basically just saute some onion and garlic, add diced potatoes, radish leaves (have to be fresh, don't use grocery store ones), and chicken broth and boil it all together. Season with thyme, salt, and pepper, then puree. We produced all of the ingredients for that one, including the chicken for the broth.
