Meet your new make-ahead breakfast hero: egg stuffed peppers. Juicy bell peppers are filled with a savory mix of eggs, liquid egg whites, turkey bacon, mushrooms, onions, and spinach, then baked until perfectly set for a colorful, protein-packed start to the day.
Preheat the oven to 400°F. Stand the hollowed peppers upright in a baking dish so they fit snugly.
In a large bowl, whisk eggs, liquid egg whites, chives, salt, and pepper. Set aside.
Heat a large skillet over medium-high heat with avocado oil. Cook the turkey bacon until almost crisp, about 4–5 minutes. Add mushrooms and onion; sauté until softened, 3–4 minutes. Stir in spinach just until wilted.
Divide the bacon–veggie mixture evenly among the peppers. Pour the egg mixture over the top, filling to about ½ inch below the rim.
Bake the filled pepper tray for 35–40 minutes, until eggs are set in the center. Rest 5 minutes before serving.
