In a 6-inch skillet melt margarine or butter. Add mushrooms, potatoes, and green onion. Cook over medium heat until potato is tender, turning occasionally.

 

Meanwhile, in a small bowl combine eggs, milk, basil, salt, and pepper. Pour egg mixture into skillet. Cook about 2 minutes or until egg mixture is set, running a spatula around edge of skillet and lifting mixture to allow uncooked portion to run underneath. Remove from heat. Top with cheese and tomatoes. Makes 1 serving.
