Preheat oven to 400°F.2. Heat oil over medium heat in a 12-inch, nonstick, ovenproof skillet (cover plastic handles with aluminum). Add potatoes and cook 10 minutes or until just tender. Add onions, peppers, and garlic and cook 5 minutes more, or until onions are translucent.

In a large bowl, beat eggs with milk, salt and pepper. Stir in cheese. Pour over potatoes and onion and transfer to preheated oven. Bake 15 to 18 minutes or until set in the middle. Loosen edges with a spatula and slide out onto a plate. Cut into 8 slices and serve with sour cream and salsa.
