Potato and Salsa Frittata

Scrub potato well, poke it a few times with a fork and bake it in the microwave on high for about 5 minutes until cooked through. Chop up one half of the potato; you only need half for this recipe (the other half is great for lunch!). In a small bowl, beat eggs, milk, salt and pepper. Heat a medium ovenproof skillet over medium heat. Spray with cooking spray. Add egg mixture, then sprinkle with potato, ham, and green onion. Drop dollops of salsa evenly throughout the frittata. Cook covered for 3-4 minutes. Sprinkle with cheese and place under broiler for another 3 minutes, until cheese starts to bubble and egg is set. Cut into pie-shaped wedges. Serve with avocado and salsa if desired.
