This recipe is very simple, it's just an omelette, but the way it's rolled, makes it taste quite differently.
Beat eggs, milk and flour in large bowl. I found that beating eggs with flour first and adding milk later, gives an omelette a smoother texture.
Pour egg mixture onto a pan (12x16) lined with parchment paper. Sprinkle eggs with prepared vegetables, ham and 1/2 cup of cheese. Bake at 350F for about 14, or until edges are almost set.
Top omelette with remaining cheese; bake 2 min or until the cheese is melted.
Roll up the omelette immediately, starting at one short end and peeling off paper as omelette is rolled. Place on platter; cut into slices.
Serve immediately, as melted cheese does taste the best.
