Blue-Cheese Burgers with Grilled Onions

Ingredients

• 1 pound ground beef sirloin
• 1 pound ground beef chuck
• Salt and freshly ground black pepper to taste
• Vegetable oil cooking spray
• Six 1/2-inch-thick slices white onion
• Canola oil
• 3 ounces blue cheese, cut into 6 slices or crumbled

Directions

1. Combine the beef in a bowl with salt and pepper, then use your hands to work everything together thoroughly. Shape the mixture into 6 patties, and chill them until it is time to cook.
2. Set up a charcoal or gas grill. Coat the grill rack lightly with vegetable oil cooking spray, then start the coals or heating elements and allow the grill to get hot.
3. Coat the onion slices with oil, then season them with salt and pepper. Put them around the cooler outer area of the grill and cook for 5 or 6 minutes, just until they start to soften. Turn them over and cook the second side for 8 to 9 minutes, until they are tender and lightly browned. Take the onions off the grill, set them aside, and keep them warm.
4. Cook the burgers for 3 to 4 minutes on the first side for medium-rare. Turn the burgers over, then add a slice of cheese to each one, or scatter about 1/2 ounce crumbled cheese over each patty. Cover the grill and cook for 3 to 4 minutes more, until the cheese is melted and the burgers are medium-rare. Finish with the grilled onions and serve.
