How can you make chili out of stew meat?

Yes. It's easy in a slow cooker. Just make the chili how you would normally make it, but before you add your stew meat to the slow cooker- brown it in olive oil in a pan/skillet to seal in the flavor as well- with some garlic, pinch of salt and pepper and Cayenne pepper (powdered). You'll be good to go then when you add it to the chili in the slow cooker. The stew meat will become nice and tender and even more so if you add an acid to the chili like a little lime juice or red wine just to help break down the meat. Make sure you cover it for at least and hour and let it sit. You'll have a great chili!
