Season the steaks with salt and pepper. Place them in a baking dish and sprinkle with olive oil, garlic powder, cumin, chili and thyme. Allow to marinate for 1 hour in the fridge.
In a frying pan, add olive oil and cook steaks on each side. Remove and cut into slices.
Add some more oil to the frying pan. Return steak slices to pan and cook on both sides. Add mushrooms, white wine and heavy cream. Cook until the sauce thickens.
