Variations—It really is incredibly easy to make your own salsa, and you can get all kinds of creative with this too. Oven-roast your tomatoes, onions, and peppers first (like in the Fire-Roasted Salsa in this book), and then mix in a food processor. Use some yellow or purple tomatoes and add in chopped bell (sweet) peppers. Try adding in some chipotles or green onions or use lemon if you have no lime, the possibilities are endless! Whatever you make, it typically keeps in the refrigerator for at least one week.
