Cheddar & Onion Beef Sliders

Directions

1. In a large skillet, heat butter over medium heat. Add onion and 1/4 teaspoon steak seasoning; cook and stir 6-8 minutes or until onion is softened. Reduce heat to medium-low; cook 40-45 minutes or until deep golden brown, stirring occasionally. Stir in wine. Bring to a boil; cook 10-12 minutes or until liquid is almost evaporated.
2. In a bowl, combine beef and remaining steak seasoning, mixing lightly but thoroughly. Shape into eight 1/2-in.-thick patties.
3. In a large nonstick skillet, cook burgers over medium heat 3-4 minutes on each side or until a thermometer reads 160°; top with cheese during the last 1-2 minutes of cooking. Serve on rolls; top with onion.
