• 1/4 cup canola mayonnaise
• 2 teaspoons chopped fresh thyme, divided
• 1/4 teaspoon hot pepper sauce (such as Tabasco)
• 1 pound lean ground sirloin
• 1 teaspoon freshly ground black pepper, divided
• 1/8 teaspoon kosher salt
• 1/2 teaspoon extra-virgin olive oil
• 4 (1/4-inch-thick) slices Vidalia or other sweet onion

1. Preheat grill to medium-high heat.
2. Combine 1/2 cup blue cheese, mayonnaise, 1 teaspoon thyme, and hot pepper sauce in a small bowl; stir well.
3. Divide beef into 4 equal portions, shaping each portion into a 1/2-inch-thick patty. Sprinkle beef evenly with 1/2 teaspoon black pepper and salt.
