- 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.
