In a medium non-stick skillet, heat the avocado oil over medium-high heat.
Add the ground turkey sausage, breaking it apart with a wooden spoon until browned and cooked through.
Toss in the diced red bell pepper and baby spinach, sautéing for 2 minutes until the peppers are tender-crisp.
In a small bowl, whisk together the egg, egg whites, sea salt, black pepper, and garlic powder.
Lower the heat to medium and pour the egg mixture into the skillet with the sausage and vegetables.
Gently fold the eggs until they are just set and fluffy, then remove the skillet from the heat.
Warm the whole wheat tortilla in a separate dry pan for 30 seconds per side until pliable.
Spoon the savory filling into the center of the tortilla, fold in the sides, and roll tightly.
For meal prep, wrap the cooled burritos in parchment paper and foil, then store in the refrigerator for up to 4 days.
