For me it is not really prepared foods per se, but saved byproducts, left over items from a dish that need to be used, or way too many items from my garden. <ul> <li>Bacon grease - in a mayo jar like any good southerner should have.</li> <li>I also keep rendered chicken fat (I do not cook duck often enough) for roasting potatoes.</li> <li>Pickled vegetables for use in salads, bloody mary's, etc. We grow zuchini, cukes, and several varieties of peppers.</li> <li>Oven roasted tomatoes: cut in half, seasoned, roasted at 200 degrees until they dry. Then pack them in oil. We grow our own tomatoes and frequently can not keep up.</li> <li>Pesto: several varieties. We make one with Pecans and Cinnamon Basil that is really good.</li> <li>Hot sauce from jalapeños and anahiems that we grow.</li> <li>If I have bought too many mushrooms (every trip to Whole Foods), I will make a quick mushroom tapenade. Sauteed mushrooms, shallots, S&P, and whatever herb I have on hand chopped finely then mixed with olive oil.</li> <li>My dad has a Meyer lemon tree that produces a ridiculous amount of fruit. In the past I have juiced them and frozen the juice in ice cube trays. This year I think I am going to try preserving them in salt and experimenting with preserved lemon in dishes.</li> </ul>
