In a heavy saucepan cook the quinoa with 2 cups water, uncovered, at high heat, for 10-12 minutes (it has to be cooked but the grains have to keep their shape). Drain the excess water.
In another pan, heat 1 tablespoon of the oil at medium-high, and saute the onion and garlic until transparent. Add cooked quinoa and pour the cream little by little, stirring constantly.
When you have used all the cream, season with salt and pepper, add the Parmesan, stirring until it has melted and mixed completely.
In another pan, heat the rest of the oil at high heat, and fry the steak (previously seasoned with salt and pepper) until it’s cooked the way you like it.
