Gather all ingredients including eggs, pizza sauce, mozzarella, pepperoni, olive oil, salt, and pepper.

Optional: If using, chop onion and bell pepper.

Heat a small skillet over medium heat and add olive oil.

If using onion or bell pepper, cook them for 2 to 3 minutes until soft.

Add pepperoni or cooked sausage and cook for 1 minute to warm and release flavor.

Spread a few tablespoons of pizza sauce in the pan.

Crack eggs into the pan over the sauce or beat them and pour in for scrambled style.

Season with salt and pepper, reduce heat to low, cover, and cook until egg whites are set and yolks are soft, about 4 to 6 minutes.

For firmer yolks, cook a bit longer.

Sprinkle shredded mozzarella over the eggs, cover, and let cheese melt for about 1 minute.

Finish with chopped basil, oregano, or red pepper flakes if desired.

Serve hot with toast or a side salad.
