In a small mixing bowl, combine the ground turkey with smoked paprika, ground cumin, and garlic powder until well incorporated.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3-4 minutes until the vegetables are tender and slightly caramelized.
Add the seasoned turkey mixture to the pan, breaking it into small crumbles with a spatula and cooking until browned and fully cooked through.
In a separate bowl, whisk together the whole egg, egg whites, sea salt, and black pepper.
Reduce the skillet heat to medium and pour the egg mixture over the turkey and vegetables, gently folding and scrambling until the eggs are just set and fluffy.
Warm the grain-free tortilla in a dry pan for 30 seconds per side until soft and pliable.
Spoon the egg and turkey scramble into the center of the tortilla, top with the sliced avocado, and roll tightly into a burrito.
