In a skillet over medium heat, cook the turkey sausage until browned and cooked through. Set aside.
In a mixing bowl, whisk together the eggs, milk, salt, and black pepper.
Scramble the eggs in a lightly greased skillet until just set.
Warm the tortillas slightly so they are easier to roll.
Divide the scrambled eggs between the tortillas.
Top each tortilla with turkey sausage, cooked breakfast potatoes, shredded cheddar, diced red bell pepper, and diced onion.
Fold in the sides and roll each tortilla into a burrito.
Lightly spray the burritos with nonstick spray or brush very lightly with oil.
Preheat the air fryer to 375°F.
Place the burritos seam-side down in the air fryer basket.
Air fry at 375°F for 6 to 8 minutes, flipping halfway through, until the tortillas are golden and crisp.
Serve warm with salsa if desired.
