Finely dice the tomato, one tablespoon of the red onion, and cilantro; combine in a small bowl with lime juice and a pinch of sea salt to create the salsa fresca.
Heat avocado oil in a large skillet over medium-high heat.
Add the ground turkey, diced bell peppers, and the remaining red onion to the skillet, seasoning with garlic powder, sea salt, and black pepper.
Cook until the turkey is browned and cooked through, breaking it into small crumbles with a spatula.
Lower the heat to medium and stir in the baby spinach until just wilted.
In a separate bowl, whisk the eggs and pour them into the skillet with the turkey mixture.
Gently scramble the eggs until set and fully incorporated with the turkey and vegetables.
Warm the tortilla in a dry pan or over an open flame for 30 seconds until pliable.
Place the turkey and egg mixture in the center of the tortilla, top with the fresh salsa fresca, and fold tightly into a burrito.
