Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe baking dish with a touch of olive oil.
Place a skillet over medium heat and add the olive oil, followed by the diced yellow onion and red bell pepper.
Sauté the vegetables for 3-4 minutes until they become tender and the onions are translucent.
Add the ground turkey to the skillet, breaking it into small crumbles with a wooden spoon as it browns.
Season the turkey mixture with sea salt, black pepper, garlic powder, and smoked paprika, stirring well to incorporate the spices.
Once the turkey is fully cooked, add the fresh spinach to the pan and toss for 1 minute until the leaves are just wilted.
Transfer the turkey and vegetable mixture into the prepared baking dish, spreading it out into an even layer.
In a small mixing bowl, crack the eggs and whisk them thoroughly until combined.
Pour the whisked eggs evenly over the turkey and vegetable base in the baking dish.
Bake in the center of the oven for 15-20 minutes, or until the eggs are completely set and the top is lightly golden brown.
