Combine 1 tablespoon olive oil, rosemary leaves, salt and pepper and rub over the meat. Place on the grill and crosshatch the meat on both sides. Continue this process until the meat reaches desired temperature.
In a hot saucepan cook the dandelion greens with 1 teaspoon garlic and 1 1/2 teaspoons oil. In a different hot saucepan cook the onions with remaining teaspoon garlic and 1 1/2 teaspoons oil. Warm the Barolo Sauce in a separate saucepan and serve over the medallions.
