Preheat the Oven: Preheat your oven to 375°F (190°C).
Prepare the Sheet Pan: Grease a large sheet pan with cooking spray or a thin layer of olive oil to prevent sticking.
Spread Vegetables: Evenly distribute the diced bell peppers, tomatoes, and onions on the sheet pan.
Crack the Eggs: Crack the eggs onto the sheet pan, spacing them evenly among the vegetables.
Season: Sprinkle salt and pepper over the eggs and vegetables. Add any additional seasonings or herbs to your liking.
Add Cheese and Bacon: Sprinkle the shredded cheese over the eggs and vegetables. If desired, add the crumbled bacon on top.
Bake: Place the sheet pan in the preheated oven and bake for approximately 12-15 minutes or until the egg whites are set, and the yolks are cooked to your desired level of doneness.
Garnish: Remove the sheet pan from the oven and garnish with chopped fresh herbs.
Serve: Carefully cut the sheet pan eggs into four portions and serve immediately.
