Prepare the pasta in boiling salted water according to the instructions on the packet. Clean, wash and halve the mushrooms. Wash and quarter tomatoes. Wash, clean and slice the zucchini.
Cut the gouda into small cubes. Wash the thyme, dab dry and chop the leaves finely. Whisk 2 eggs and some thyme and season with salt and pepper. Heat 1 teaspoon of oil in a pan (16 cm Ø).
Fry 1/4 of the zucchini and mushrooms for about 3 minutes. Add 1/4 of the pasta, 1/4 of the tomatoes, cheese and 2 whisked eggs. Let the egg mixture set slightly, stirring lightly a few times with a spatula (loosen up).
Place the omelette on a plate and let it rest in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 2-4 minutes. Prepare 3 more omelettes in the same way. Green salad tastes good with them.
