This is one of my “go to” favorites for school lunches that goes over well with the kids. You can start with a pot of my homemade black beans, these slow cooker pinto beans, or turn to your pantry for beans from a can or a box.

A warm thermos of Easy Cheesy Thermos Beans is tasty, filling, and nourishing. Pack a few favorite accompaniments to go along for the ride and lunch just got a little more interesting.

Easy Cheesy Thermos Beans

To help keep the beans warm during the school day, preheat the thermos by filling it with boiling water while the beans heat on the stove. When the bean are hot, dump the water out of the thermos and immediately fill it with the beans and cheese and screw on the lid.
