Brown hamburger with onion and drain excess grease. Add
remaining ingredients except tortillas and cheese and heat through.
(You may add salt to taste.) Layout tortillas and divide meat
mixture and cheese among them. Roll up in plastic wrap, place in
gallon sized ziplock freezer bags, and freeze.
To serve, place one wrapped frozen burrito on a plate and
microwave for 1 ½ minutes or so. Using kitchen shears, slice
through the plastic wrap along the length of the burrito and
discard. (If you discover the middle is still cold, heat it up a little
more in the microwave.)
This recipe may be doubled.
