Revamped Tex-Mex Frittata

Heat oil in a large skillet over medium heat.  Add frozen potatoes, arrange in a single layer and cook for 5 minutes.  Stir well and cook, without stirring, for an additional 5 minutes.  Transfer to an 8-inch square baking dish sprayed with non-stick cooking spray.

Whisk together egg substitute, water, oregano, salt and pepper. Pour over potato mixture.  Sprinkle with cheese.

Bake uncovered at 350 degrees for 45 minutes or until edges are golden.  Allow to stand for 5 minutes before topping with salsa.
