Mexican Chicken Chili

I think the official title once was "Chicken Tortilla Soup," but I think it turns out much more like a chili... and there is no tortilla involved when I eat it, so I came up with a better name. :)

3 or 4 chicken breasts (can even be frozen straight from the freezer)
2 cans stewed tomatoes (seasoned, whichever strikes your fancy)
1 can corn
2 cans black beans
1 can green chilis
1 small bottle salsa

Simmer in crockpot all day on low (even with frozen chicken). Serve over tortilla chips with cheese, or serve over rice (or pearled barley, my new favorite).
