Silky and sweet, these onions add a sophisticated touch to adults' burgers (adventurous younger eaters will enjoy them, too).
Ingredients
2 tablespoons olive oil
2 large onions, cut into 1/8-inch-thick slices
1/4 teaspoon salt
1/8 teaspoon ground black pepper
1/3 cup canned beef broth
1/2 cup purchased barbecue sauce
1 1/2 tablespoons apple cider vinegar or white vinegar
Directions
Heat oil in large skillet over medium-high heat. Add onions, salt and pepper; cook until onions begin to brown, stirring frequently, about 8 minutes. Add broth, barbecue sauce and vinegar. Reduce heat to medium; simmer until sauce thickens, stirring occasionally, about 15 minutes. (Can be made 1 day ahead. Cover; chill. Rewarm before serving.)
