Turkey Melt with Caramelized Onions and Spicy Pumpkin Mayo

For the onions:
In a large saute pan over medium heat, melt butter in olive oil, swirling to combine. Add sliced onions, salt and pepper and cook for about 2 minutes or until the onions begin to soften. Stir in sugar. Continue cooking onions for 20 minutes. Be sure to stir often to prevent the onions from burning. Remove onions from heat and set aside.

For the mayonnaise:
In a small bowl, combine mayonnaise, pumpkin, chili powder, paprika and salt. Set aside.

For the sandwiches:
Heat a griddle pan over medium heat. Butter the bottoms of 4 slices of bread and place on the griddle pan, buttered side down. Top each slice of bread with a slice of turkey, a slice of cheese, 1 tablespoon of pumpkin mayo, 1-2 tablespoons (eyeball this) of caramelized onions and another slice of bread. Butter tops of each sandwich.

Cook sandwiches on each side for roughly 3-5 minutes or until golden brown. Remove from griddle and serve!
