Rich and delicious, grilled chuck steak is a definite people pleaser. Start with a thick chuck steak and marinate it with fresh garlic and spices in olive oil. Flop it on the grill and watch it sizzle. The natural sweetness of red onions and tomatoes are enhanced by charring over the open fire. Serve the steak with the onions and tomatoes on the side. Add a baked potato for a complete meal.
