Cook sausage and scrambled eggs separately. Season eggs with salt and pepper.
Warm tortillas in the microwave or dry skillet so they're pliable.
Lay a tortilla flat. Layer in the center: a few spoonfuls of eggs, sausage, black beans, salsa, and cheese.
Fold in the sides of the tortilla, then roll tightly from the bottom up into a burrito shape.
Wrap each burrito tightly in foil and place in a zip-lock bag. Freeze for up to 1 month.
To reheat from frozen: unwrap foil, wrap in a damp paper towel, and microwave 2 to 3 minutes, flipping halfway.
