Grease a standard muffin tin really well with butter or oil.
Pre-heat the oven to 350°F.
Remove the stem and seeds and chop the red bell pepper into small bite size pieces, then set them aside.
Wash, remove the root, then slice one green onion (white and green parts) then set it aside.
To a 10-inch dry skillet add the 4 oz of pancetta and sauté for 1 minute then add the red bell pepper and 1/2 tsp of salt. There should be enough grease from the pancetta to fry the peppers, if not then add 1-2 tbsp of extra virgin olive oil.
Cook until the red bell pepper is soft and slightly charred, and the pancetta is slightly crispy.
Once the peppers are soft and the pancetta is slightly crispy remove them from skillet using a slotted spoon and place them into a bowl. Then set the bowl aside to cool about 10 minutes.
Crack the 8 eggs into a large bowl, then add the 3/4 cups of milk, 1/2 tsp of salt, 1/4 tsp of black pepper. Whisk until well combined then evenly pour into the muffin tin.
To each egg bite add a sprinkle of green onion, and a bit of the red pepper/pancetta mixture using them all up.
Top each egg bite with the 1/2 cup of mozzarella cheese.
Place the muffin tin onto a baking sheet and place onto the middle oven rack.
Bake for 30-35 minutes or until the egg bites are set.
Once the egg bites are cooked through remove them to a cooling rack for 5 minutes then remove them gently from the muffin tin and place onto a cooling rack until cooled.
