Crack the eggs into a large bowl and whisk until well combined. Season with salt and pepper.
Spray skillet with olive oil spray. Heat a large non-stick skillet over medium low heat and cook scrambled eggs. Turn off the heat and let them cool.
Prepare a burrito prep station with other ingredients. Tear 12 pieces of foil to wrap each burrito.
Place tortilla/wrap on top foil. Then layer with spinach, black beans, eggs, cheese and salsa.
Wrap the burrito - You can fold in the sides and then roll it up OR you can just roll it more like a wrap. Wrap the burrito in the piece of foil.
Repeat with the remaining burritos. Then place the foil wrapped burritos into a large freezer-safe plastic bag. Be sure to label it "Freezer Southwest Breakfast Burritos" and include the date that you made them. You can freeze these up to 3 months.
When you are ready to eat the burritos, defrost (as many as needed) overnight in the refrigerator. Then reheat in the microwave in 30 second increments until contents are hot.
