Mix beans, cheese and Rotel in a medium sauce pot over low heat until combined and warmed. (If you prefer a thicker filling, you should drain the Rotel.)
Cut 12 pieces of foil large enough to wrap burrito and lay them in a stack.
Lay a tortilla on top of the foil stack and add approx. 1/2 cup filling to the center.
Fold tortilla into burrito and wrap with foil.
Repeat steps 3 & 4 until all filling is used.
Place burritos in labeled gallon freezer bags and freeze until ready to serve. Burritos will last up to 3 months in the freezer.
For serving: Remove foil from frozen burrito and cook in microwave 2-3 minutes or until warmed throughout. You may also cook in a toaster oven at 350 for 15 minutes or until burrito is hot in the middle.
