1 small red onion, chopped
1 tablespoon olive oil
1-1/4 teaspoons salt, divided
1/2 cup mayonnaise
1/2 teaspoon whole peppercorns, crushed
1-1/2 pounds ground beef

Steps:

Place onion on a greased baking sheet. Drizzle with oil and sprinkle with 1/4 teaspoon salt; toss to coat. Bake at 400° for 8-12 minutes or until tender. Cool slightly. In a small bowl, combine the mayonnaise, crushed peppercorns and onion mixture; set aside., Sprinkle beef with remaining salt; gently mix. Shape into four patties. In a large skillet, cook patties over medium heat for 6-8 minutes on each side or until a thermometer reads 160° and juices run clear. Serve on rolls with mayonnaise mixture and, if desired, tomato and lettuce.
