Make the pasta plates al dente. Drain and set aside. Preheat the stove to 175 degrees.
Heat oil in a large frying pan and sauté tomatoes, onions, garlic and mushrooms. When onions are translucent, add culinary herbs, coarsely chop spinach and also add to skillet until “wilted”. Stir well. Simmer.
Mix half of the mozarella with the other cheeses in a large baking bowl. Add the vegetables to the cheese mixture and fold in well. Layer the pasta sheets alternately with the cheese/vegetable mix in a suitable heatproof dish. Top with the remaining mozzarella and bake for 30 min. Rest for 5-10 min. before serving.
Our tip: If you like to cook with fresh herbs, it is best to get kitchen herbs in pots – so you always have everything ready!
