Frittata has been my go-to breakfast at home lately. This will do a 10" cast iron skillet perfectly:
4-6 slices bacon, diced
1 medium onion, diced
1 green pepper, diced
optional: 1 firm tomato, diced
6-8 large eggs
splash milk
salt/pepper
shredded cheese
Preheat oven to 400F.
Crack all the eggs into a large bowl, add milk, salt and pepper, whisk or blend well.
In a cast-iron skillet, cook the bacon to "just crispy", then set aside to drain. RESERVE 1-2 TBSP GREASE.
In the leftover grease, add the peppers and onions and sautee over medium heat until the onion is just starting to get tender.
Add the bacon back into the skillet.
Pour the egg mixture into the skillet, give it one quick stir with a spatula, and then DON'T TOUCH IT.
Let it cook until just setting around the edge.
Scatter the cheese over the top, and transfer the whole pan to the oven.
Bake ~10 minutes, until the egg is set all the way through and the cheese is melted.
