Premade chili, or a thick lentil curry, will be your best bet if you're doing anything active on this camping trip. Cook it ahead of time, throw it in the cooler, and heat it up. You may want to add a grain if you don't want to do rice before or after on the same burner (minute rice will be easy though).

I personally love to dehydrate the above but that tends to be for backcountry canoe camping and hiking, where weight and volume matter a lot.
