Caramelized Onion-and-Cranberry Cheese Toasts

In a 1-1/2-qt. slow cooker combine onions, apple, and cranberries. Top with butter. In a small bowl combine vinegar, brown sugar, and orange zest; pour over mixture in cooker.

Cover and cook on low 5 to 6 hours or high 2-1/2 to 3 hours. (If no heat setting is available, cook 4 hours.)

Spread toasted bread slices with cheese. Using a slotted spoon, spoon 1 tablespoon onion mixture onto each toast. If desired, top with cilantro or parsley.
