Lay out 5 burrito wraps. When all ingredients have cooled, start with the egg and spoon the eggs, evenly, in the middle of each wrap then top with sausage and spinach. If using cheese, top with cheese.
Roll up and tightly wrap each burrito in foil and place into a large meal prep container or freezer bag.
To reheat: remove the foil, wrap in a paper towel and place burrito on a microwave-safe plate. Cover and heat in 30-second increments until done, about 2- 2 1/2 minutes. Make sure to check frequently so they don't overcook.
