Cook the sausage, loose, in a pan until browned.

Add all the eggs and cook until the eggs are done. While the eggs are cooking, you can shred the cheese.

Line the tortillas up on a big baking pan.  Fill each tortilla with some egg mixture and top with cheese (and potatoes, if using).

If you're freezing them, roll them up and place them on the baking pan seam-side down before putting the pan into the freezer for at least 4 hours.  I leave mine overnight.

Remove the pan from the freezer, transfer the burritos to a large storage bag, and put it back in the freezer. (This is so they won't all freeze to each other in a giant ball.)

When ready to eat them, place the desired number on a baking pan and bake at 350 for about 10 minutes.  Enjoy!
