Chili
Janel got this recipe from a friend (Becky Lehman) and when we make chili, this is the recipe we usually fall back on. You can adlib with a few things (we've added corn and mushrooms, for example) and if you need a little protein, you can add ground meat easily.
It's not as good as the fresh salsa, but it does last longer which can be helpful if you have a lot of tomatoes to use and want to save some jars for the future. I believe this one originated with the "More With Less" cookbook.
