In a medium bowl, whisk together the eggs and milk until combined. Season with salt and pepper, and set aside.
Heat a large skillet over medium-high heat. Crumble the sausage in the pan, cooking until no longer pink. Drain any fat, and place the sausage in a bowl. Set aside.
Wipe out the skillet, and return the pan to the heat. Heat the oil over medium-high heat. Add the potatoes and peppers to the pan, and cook until the potatoes are browned and the peppers are soft, about 8-10 minutes. Place the veggies in the bowl with the sausage, and return the pan to the heat.
Scramble the eggs over medium-high heat until cooked through. Turn the heat to low, and add the potatoes, peppers, and sausage back to the pan. Add the can of black beans. Season with salt and pepper as necessary. Stir until everything is warm.
Divide the filling between the eight tortillas, and sprinkle 1 Tablespoon of cheese over each tortilla. Wrap burrito-style (see photos above to learn how!)
If serving immediately, either microwave the burritos until warm or cook for about 10-15 minutes in the oven at 350°F. To take it to the next level, heat a skillet over medium-high heat with a little oil. Grill the burrito on each side until crispy. Enjoy with salsa, guac, and hot sauce!
To freeze, wrap each burrito in beeswax wrap, plastic wrap, or tinfoil. Store in an airtight container in the freezer for up to two months. To heat, microwave for 3-5 minutes until warm in the center. You can also heat them at 350°F for 15-20 minutes. To take it to the next level, heat a skillet over medium-high heat with a little oil. Grill the burrito on each side until crispy. Enjoy with salsa, guac, and hot sauce!
