Rinse the spinach and dry it well with paper towels. Wipe the mushrooms with a damp paper towel and slice them.
Tip · Dry the spinach really well, or it releases water into the skillet and the omelet turns soggy.
Brown the mushrooms
Melt half the butter (about 7 g) in the skillet over medium-high heat. Add the mushrooms and brown them 5 minutes, stirring now and then.
Tip · Don't stir the mushrooms too early and don't salt them until the end, so they brown instead of boiling.
Wilt the spinach
Add the spinach to the skillet and stir for 2 minutes until wilted. Salt, pepper, then tip everything onto the plate.
Beat the eggs
Crack the 4 eggs into the mixing bowl, add a pinch of salt and pepper, then beat them with a fork until smooth.
Cook the eggs
Wipe out the skillet, melt the rest of the butter over medium heat and pour in the eggs. Let them set for 2 minutes, pulling the edges toward the center with the spatula.
Fill the first half
While the omelet is still a little runny, spread the mushrooms and spinach over one half. Sprinkle half the shredded cheese (25 g) on top.
Add the rest of the cheese
Sprinkle the rest of the shredded cheese (25 g) over the eggs on the other side of the filling. Cook 1 minute over low heat so the eggs are fully set.
Fold and serve
Fold the omelet in half with the spatula and leave it 1 minute so the cheese melts. Cut it in two and serve right away.

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!
