The next morning, after we see what Santa left in our stockings, we enjoy breakfast. I created this one-dish casserole so I wouldn't have to spend all my time in the kitchen." Ingredients 1 pound bacon slices2 cups diced potatoes2 cups diced ham or cooked ground sausage2 red bell peppers, chopped2 green bell peppers, chopped1 1/2 cups chopped onions2 (2-ounce) cans sliced ripe olives, drained1 cup sliced mushrooms12 eggs3 cups milk1 cup biscuit mix1 1/2 teaspoons salt1 teaspoon black pepper1 teaspoon garlic pepper1/2 teaspoon dried parsley2 cups shredded mild Cheddar2 cups shredded mozzarella1 (16-ounce) container salsa1 (16-ounce) carton sour cream Instructions Preheat the oven to 375 degrees F. Grease a 13 x 9-inch glass baking dish. Heat a large skillet over medium-high heat. Add half of the bacon and cook until crisp, stirring frequently. Drain on paper towels; discard the drippings. Repeat with the remaining bacon. Crumble and set aside. Layer the potatoes, ham, red pepper, green pepper, onion, olives, mushrooms, and bacon in the order listed in the prepared pan. Whisk the eggs in a medium bowl until well beaten. Add the milk, biscuit mix, salt, black pepper, garlic pepper, and parsley and stir until well blended. Pour evenly over the potato mixture; cover the casserole with foil. Line the oven rack with foil to catch any drippings. Bake for 1 hour, uncover, and bake for 20 minutes longer, or until a knife inserted in the center comes out clean. Sprinkle the Cheddar and mozzarella evenly over the top and return to the oven for 10 to 15 minutes, until the cheese melts and begins to brown. Remove from the oven and let stand 15 minutes. Top each serving with a dollop of salsa and sour cream. Recipe by Debra Amunrud, Glencoe, Ark.
