Remove from oven, sprinkle with a pinch of cheese on top of each. Bake for 25 minutes. Remove from oven, top each with a pinch of cheese.
Omelets will rise beautifully as you bake them but will fall, as the result, of cooling. Let the cheese melt & serve with a garnish of fresh tomato salsa. Chef Notes: You can mix egg mixture the evening before and store in refrigerator overnight. Also, you might like to dice all fresh veggies the night before so you can quickly assemble them in the morning. You may find this pan @ https://amzn.to/3roZAVs
