These bean burritos are great to make ahead for last-minute grab-and-go meals. Assemble the burrito when the beans are at room temperature so that they don't get soggy in the freezer. Once assembled, wrap the burrito in foil or place it in a freezer-safe container. Freeze for up to 3 months. To reheat, remove the foil and reheat in the microwave on a plate for 2-3 minutes, flipping over halfway through.
