Heat a non-stick skillet over medium heat and lightly coat with cooking spray.
Whisk the whole eggs and liquid egg whites together in a bowl until fully combined; season with salt and pepper.
Add the ground turkey sausage to the skillet and heat for 2 minutes until sizzling.
Pour the egg mixture into the skillet with the turkey and cook, stirring frequently with a rubber spatula, until the eggs are scrambled and set.
Stir in the black beans during the last 30 seconds of cooking to warm them through.
Warm the protein tortilla in a separate dry skillet or microwave for 15 seconds to increase pliability.
Spread the Greek yogurt onto the center of the tortilla, then layer the egg and turkey scramble on top.
Sprinkle the shredded cheese over the hot filling and add the avocado slices.
Fold the sides of the tortilla inward and roll tightly from the bottom to create a sealed burrito.
Optional: Place the burrito seam-side down in the skillet for 1 minute to toast the exterior and seal the fold.
