Peppered Beef Frittata

Good morning Sunshine! Another breakfast treat from SBD Recipes. In their book, originally it's Smoked Salmon Frittata. I substituted peppered beef for smoked salmon, actually any meat will do like ham. I also omitted some of the ingredients not available, just made it a simple frittata by adding cheese.

8 stalks of fresh asparagus

1 tablespoon extra-virgin olive oil

2 slices of peppered beef, chopped
1/2 medium onion, chopped

2 eggs

1/4 cup fresh milk

pinch of ground pepper
mozzarella cheese (optional)

In a pan, saute onion until soft. Add asparagus and peppered beef. Remove from the heat. Combine and whisk together the eggs and milk until the whites and yolks are completely blended. Add the beef mixture, seasoned with pepper. Heat the pan over the medium heat, pour in the egg mixture the bottom is cooked. Sprinkle with the cheese. Bake in the oven until the eggs are set and cheese has melted.
