Peel the potatoes and cut them into small cubes, about 1 cm. Peel the onion and slice it thin.
Cook the potatoes
Heat the olive oil (1 tbsp) over medium heat in the skillet, add all the potatoes and brown them, stirring now and then. Then cover and let them cook over low heat until tender.
Tip · Stir only a little at first so the potatoes brown instead of breaking, then cover to let them steam through.
Add the onion
Add the sliced onion to the potatoes and let it turn translucent over medium heat, stirring. Season with half the pinch of salt.
Wilt the spinach
Wash the spinach (200 g), add it to the skillet and stir until it's fully wilted. If there's water left in the bottom, let it cook off.
Beat the eggs
Crack the 4 eggs into the mixing bowl, add the rest of the salt and the pepper, then beat them with a fork. Tip the potatoes, onion and spinach into the eggs and stir.
Cook the omelet
Put the mixture back in the hot skillet over low heat, spread it out and let it cook without stirring. Cover so the top sets, until it's no longer runny.
Flip and serve
Slide the omelet onto a plate, flip it back into the skillet and cook the other side for 2 minutes. Cut it in two and serve.
Tip · To flip without breaking it, set the plate upside down on the skillet, turn it all over in one move, then slide the omelet back into the skillet.

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!
