Another trick I just used. My wife doesn't like onions, peppers, or fresh tomatoes in her chili. So I use salsa to add the flavor of all those things. It also helps in a pinch if you can't find those things fresh in the kitchen. And then she likes noddles in the chili. Of course, by then it's not really chili, but the things one must do for love.

Oh, sometimes i throw a V8 or two in for the salt content and healthyness.
