Grease a 10-inch omelet pan with margarine over a medium heat. Have all other ingredients ready to assemble quickly after the eggs are cooked. Put the eggs in a pan and cook slowly over medium heat. With a spatula, push the eggs to the center of the pan. Remember that this is an open omelet so do not fold over. As the eggs begin to seal on the bottom, keep folding the loose eggs under the cooked portion. When almost all the loose egg is cooked, flip the eggs over. Lay the cooked eggs flat on a plate. Spread with sour cream, and then place potatoes on the eggs, followed with mushrooms, tomatoes and bacon. Top with feta cheese.
