Give the 150 g of mushrooms a quick rinse, pat them dry and slice them thin. Rinse the 100 g of spinach and drain it well.
Sauté the mushrooms
Heat the olive oil (1 tbsp) in the skillet over medium-high heat. Add the mushrooms and brown them, stirring now and then.
Tip · Don't stir the mushrooms right away, let them brown for a few minutes first. They'll release less water and won't boil.
Wilt the spinach
Add the spinach to the skillet with the salt and pepper. Stir until it's wilted and the water has cooked off, then tip everything onto the plate.
Tip · Press the cooked spinach against the side of the skillet with the spatula to squeeze out the water, or the omelet will be soggy.
Beat the eggs
Crack the 4 eggs into the mixing bowl and beat them with a fork until smooth. Add a pinch of pepper.
Pour in the eggs
Put the skillet back over medium-low heat and pour in the beaten eggs. Spread the mushrooms and spinach over the whole surface.
Cook the omelet
Cook over low heat, loosening the edges with the spatula, until the bottom is set and the top is barely runny.
Add the feta
Crumble the 50 g of feta over one half of the omelet. Cover the skillet so the top finishes cooking through, with no runny egg left.
Tip · Feta is already salty, so taste before adding more salt. Serve the omelet with a green salad or toast.
Fold and serve
Fold the other half of the omelet over the feta with the spatula. Cut it in half and serve right away.
And there you go, it's readyCheck off every step to celebrate.

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!
