We have an amazing chili recipe with a story attached (DH got it from a homeless guy he let stay with him back when he was single and in college). Everyone we've given it to LOVES it and raves that he should enter a chili contest. But... it is far from simple and is loaded with bell peppers so the kids probably won't like it.
When I was a kid my mom made simple chili with McCormick's chili seasoning packet. It was almost exactly like
THIS RECIPE except with dark red kidney beans (they were the only beans us kids would eat).
