Question: how to heat up canned refried beans?
Answer: Canned refried beans are already prepared, so all you need to do is heat them up! Your choice: microwave (but be sure to cover them) or stovetop in your choice of pan or pot or skillet. Stir them of course & you'll probably have to add some water to keep them from drying out. Just heat & eat if you're in a hurry.
