Melt the butter in a pan and sauté the sweet potato with a dash of allspice until tender (approximately 3-4 minutes). Set aside to cool.
Place the cheese, wine or apple juice, allspice, and thyme in a saucepan. Heat over low-medium heat until the cheese is completely melted.
Plate the Mission Rounds Tortilla Chips and pour the melted cheese on top. Garnish with the heirloom tomatoes, sweet potatoes, and chives. Enjoy!
