Preheat the oven to 350℉ and grease a 9x13" casserole dish.
Heat a skillet over medium high heat and cook the bacon until crispy. Drain the grease and set aside and place the pan back on the burner.
6 oz Bacon
Using the little bit of grease left in the pan after draining, add the peppers over medium heat and saute until tender, about 3 minutes and add the onions. Cook another 2-3 minutes and add the seasoning, stirring to combine. Remove from the heat.
1 Red Bell Pepper, ½ Green Bell Pepper, ¼ Cup Red Onion
Chop the cooled bacon.
Beat the eggs and milk in a large bowl. Stir in the bacon, peppers and onions mixture, seasonings and cheese, reserving a small amount of cheese to sprinkle on top.
11 Eggs, ½ Cup Skim Milk, ½ teaspoon Salt, ¼ teaspoon Black Pepper, ¼ teaspoon Garlic Powder, ¼ teaspoon Onion Powder, 2 Cups Sharp Cheddar Cheese
Pour into the prepared dish and add remaining cheese, and bake until a knife inserted into the middle comes out clean, about 30-40 minutes.
