Rinse the lettuce leaves under cold water to remove any dirt. Shake them gently or spin them dry in a colander.
Slice the mushrooms
On the cutting board, cut the mushrooms into thin slices with the knife.
Cook the mushrooms
In the nonstick skillet over medium heat, add a tablespoon of olive oil. Add the sliced mushrooms and cook for 5 minutes, stirring now and then, until golden.
Tip · To keep the mushrooms from releasing too much water, don't crowd the skillet, and cook them over medium heat without a lid.
Beat the eggs
Crack the 6 eggs into a bowl and beat them with a fork with a pinch of salt and pepper until smooth.
Cook the omelet
Spread the beaten eggs over the mushrooms in the skillet. Cook over low heat 3 to 4 minutes without touching, until the edges start to set. Then fold the omelet in half with a spatula and cook for 1 minute more.
Tip · If the omelet seems too runny, cook it 1 to 2 minutes longer over very low heat without touching.
Dress the salad
In a salad bowl, drizzle the balsamic vinegar over the lettuce. Toss gently to coat the leaves.
Serve
Set the mushroom omelet on a plate and serve with the dressed green salad.

Pantry salt, oil and spices aren't counted. Your store and your brands will move the total, but the ballpark is right.
How long does it keep?
Eat it fresh. An omelet is best soft, fresh out of the pan: reheated, it turns rubbery. Make it the day you eat it, it's done in 5 minutes!
