I like beans! I have only eaten pinto beans with BBQ two times when traveling in texas and trying places. All the other times, it has been baked beans. To be honest, I skip out on them at my family functions.
I have never been asked to make the beans. My mom n law has the original recipe, and everyone else follows it. Canned baked beans, brown sugar, mustard, ketchup, pepper, onion, bacon slices on top..bake. My preference is to make them less sweet than everybody else likes them, but again...never allowed or asked. I would throw in some peppers (green/jalapeno), some spicy bbq sauce maybe, and change up the type of beans (maybe have multiple types?). Still a little sweet, but not overly sweet.
