Garlic-Thyme Burgers with Grilled Tomato

From Cooking Light



Ingredients:
1 tablespoon chopped fresh thyme
1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
2 garlic cloves, minced
1 pound ground sirloin
4 (1/2-inch-thick) slices beefsteak tomato
1 tablespoon Dijon mustard
4 (2-ounce) Kaiser rolls or other sandwich rolls
4 baby romaine lettuce leaves

Directions:
Heat a grill pan over medium-high heat. Combine first 5 ingredients in a medium bowl. Divide mixture into 4 equal portions, shaping each into a 1/2-inch-thick patty. Add patties to pan; cook 4 minutes on each side or until desired degree of doneness. Remove patties from pan. Add tomato slices to pan; cook 1 minute on each side. Spread about 3/4 teaspoon mustard over bottom half of each roll; top each with 1 lettuce leaf, 1 patty, 1 tomato slice, and top half of roll.

Comments:
Adam was reluctant to grill the tomatoes at first, but I think we were both glad he did. They were warm, and soft, and sweet. Great idea! The burgers themselves had a nice flavor from the thyme as well.
