Ingredients:
- 1/2 cup Mayonnaise
- 2 tbsp Apple Cider Vinegar
- 1 tsp Spicy Brown Mustard
- 1 tsp Prepared Horseradish
- 1/2 tsp Coarse Black Pepper
- 1/4 tsp Garlic Powder
- 4 slices Sourdough Bread
- 1.5 cups Shredded Chicken Breast
- 4 slices Monterey Jack Cheese
- 2 slices Sharp White Cheddar
- 1/4 cup Thinly Sliced Red Onions
- 2 tbsp Unsalted Butter
Instructions:
- Emulsify the sauce. Whisk 1/2 cup Mayonnaise, 2 tbsp Apple Cider Vinegar, 1 tsp Spicy Brown Mustard, 1 tsp Prepared Horseradish, 1/2 tsp Coarse Black Pepper, and 1/4 tsp Garlic Powder in a small bowl until smooth and velvety.
- Infuse the chicken. Fold 1.5 cups Shredded Chicken Breast into the sauce. Note: This ensures every fiber of the meat is coated and protected from drying out.
- Prepare the foundation. Freeze your butter for 10 minutes before you start. Grate 2 tbsp Unsalted Butter onto one side of each of the 4 slices Sourdough Bread. On the buttered side, place one slice of Monterey Jack cheese.
- Distribute the protein. Layer half of the white BBQ chicken mixture over the cheese, add sliced red onions, and top with a slice of sharp white cheddar.
- Seal the assembly. Place the second slice of sourdough on top, buttered side facing outward.
- Initiate thermal transfer. Place the sandwich into a cold cast iron skillet and turn the heat to medium-low. Cook for 4 minutes per side until the bread is golden brown and the cheese is fully melted.
