Chop the onion and sauté it. Let it cook a bit, then add the minced garlic. Next, add the washed spinach and mushrooms. Season with salt and pepper.

Add a few tablespoons of tomato sauce. Add the uncooked pasta and some water (not too much, so the sauce doesn't become too watery). Once the pasta is cooked, remove from heat and add a couple of tablespoons of whipped cheese (to taste). And it's ready to eat!
