In a small bowl, combine the ground turkey with dried sage, garlic powder, onion powder, red pepper flakes, half the sea salt, and half the black pepper to create a clean breakfast sausage blend.
Heat the olive oil in a non-stick skillet over medium-high heat.
Add the seasoned turkey to the pan, breaking it into small crumbles with a spatula, and cook until fully browned and cooked through.
Add the diced bell peppers and onions to the skillet; sauté for 3-4 minutes until the vegetables are tender-crisp and the onions are translucent.
Stir in the baby spinach and cook for 1 minute until just wilted, then transfer the entire sausage and vegetable mixture into a large breakfast bowl.
Wipe the skillet clean and return it to medium-low heat. Whisk the eggs with the remaining salt and pepper.
Pour the eggs into the skillet and cook, stirring gently and constantly, until soft, silky curds form.
Top the sausage and spinach base with the scrambled eggs and finish with fresh avocado slices.
