Instructions

1. Place the steak between 2 pieces of plastic wrap and use a mallet to pound to 1/4- inch thickness. Cut into 4 equal pieces, diagonally, against the grain.
2. In a small bowl, whisk together 1 tablespoon of the olive oil, balsamic vinegar, sugar and garlic. Put the steak into a sealable plastic bag with the marinade and let sit for 30 minutes at room temperature, or 1 hour in the refrigerator.
3. Meanwhile, in a small bowl combine the blue cheese and buttermilk. Use a fork to mash the crumbles until its creamy. Stir in a dash of Worcestershire and set aside.
4. Preheat your grill over medium-high heat. Cut the onion into 1/4-inch rounds brush both sides with the remaining tablespoon of oil and grill 6 minutes per side. Separate into rings and set aside.
5. Remove the meat from the marinade, pat dry and season both sides with salt and pepper. Discard the marinade. Cook the meat on the grill for about 3 minutes per side for medium rare.
6. Arrange 3 radicchio leaves and a pile of onions on each serving plate. Top with a piece of steak. Drizzle with blue cheese sauce and garnish with chopped parsley.
