- Brown The Mushrooms
Heat olive oil in the skillet over medium heat, add mushrooms, and cook until browned and most moisture has evaporated. · 5 min

- Cook First Eggs
Melt 7 g butter in the skillet over medium low heat, pour in half the egg mixture, and stir gently until soft curds form. · 2 min

- Fill First Omelette

- Fold First Omelette
Fold the plain side over the filling, slide the omelette onto a warm plate, and keep it covered while you cook the second. · 1 min
