How to Make It
Combine the first 3 ingredients, stirring until smooth. Spread about 1 tablespoon cream cheese mixture over 1 side of each bread slice. Top each of 2 bread slices with 6 apple slices and remaining 2 bread slices, cream cheese side down. Lightly coat sandwiches with cooking spray.
Heat a grill pan over medium heat; add sandwiches to pan. Cook 2 minutes on each side. Cut each into 4 triangles.
Combine water and unwrapped caramels in a microwave-safe bowl. Microwave at HIGH for 30 seconds or until caramels melt, stirring after 15 seconds. Drizzle sandwiches with caramel.
