In a medium skillet, heat the EVOO, 1 turn of the pan, over medium-high heat. Cook the sausage, breaking it up into little bits with a wooden spoon, until browned. Drain off all but a few tablespoons of fat from the sausage. Reduce the heat to medium, push the sausage to the sides of the pan, add the onion and garlic to the center and cook until tender, 6 to 8 minutes. Mix into the sausage and remove the pan from the heat.
