I also use salsa in my chili, but I prefer Joe-T's medium. I just use the whole jar. Chili is always better the second day, reheated on the stove or in the crock pot. Microwaving leftover chili is not acceptable. I usually us a combination of meats like venison and pork or venison and beef. I keep a bag of dehydrated refried beans (I don't remember the brand) and use them to thicken my chili instead of flour, when it needs thickening. I don't add them to add beans, just to soak up any extra moisture. Also, beer or left-over black coffee can be used instead of water.
