Preheat your oven to 400°F (200°C) and line a sheet pan with parchment paper.
Arrange the bread slices on the pan, leaving space between each slice.
Crack an egg onto each slice of bread, ensuring the yolk stays intact.
Sprinkle diced peppers, onions, and cheese evenly over the eggs.
Add bacon or ham if using.
Season with salt and pepper.
Bake for a duration of 12 to 15 minutes, or until the eggs have fully set and the cheese has melted.
Once removed from the oven, allow it to cool for 2 to 3 minutes prior to serving.
