I like my fillings, aside from the cheese, mixed in the egg part of the omelet rather than sliding about, so this uses that technique. The result is more of a folded frittata than a classic omelet, but it's very tasty. This variation on fillings is hearty and flavorful.

Recipe Instructions
Step 1
Lightly whisk the eggs with the milk in a bowl to break the yolks and integrate the milk; season with 4 pinches black pepper and 2 pinches garlic salt.
Step 2
Heat olive oil in a non-stick skillet over medium heat; cook and stir mushrooms and onion in hot oil until the onion softens, about 5 minutes.
Step 3
Spread the mushrooms and onion into the bottom of the skillet so it forms an even layer.
Step 4
Sprinkle spinach evenly across the top of the mushroom and onion layer.
Step 5
Pour egg mixture over the vegetables.
Step 6
Cook until the top of the egg is set, 3 to 5 minutes.
Step 7
Sprinkle Stilton cheese and mozzarella cheese over the cooked egg; cook until the mozzarella begins to melt, fold the omelet in half around the filling to make a half-moon.
