By carvalhohm

Ingredients

• 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
• 4 kaiser rolls, split and toasted
• Optional ingredients: tomato slices and lettuce leaves

Preparation

Step 1

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. Yield: 4 servings.
