Heat the oil in a pot. Sauté onion and garlic in it. Dust with flour and sauté briefly. Add spinach and 5 tablespoons of water and cook over low heat for about 12 minutes.
Add milk, cream and cheese to the spinach and bring to the boil while stirring occasionally. Simmer for another 4-5 minutes.
Drain the pasta and season the sauce with salt, pepper and nutmeg. Mix cheese-spinach sauce with noodles and serve. Sprinkle with pink berries.
