For the Hot Wings, move rack to the middle of the oven and preheat broiler.

Bring a large pot of water up to a bubble and par-cook the chicken for about 5 minutes. Drain and pat dry.

Place a small saucepot over medium heat, melt the butter, add the garlic and allow to brown, about 1-2 minutes. Whisk in the Sriracha and white wine vinegar until combined then set aside.

Line a baking pan with parchment paper. Place the wings onto the baking pan and broil until golden brown and crispy on both sides.

Transfer the wings to a large bowl, pour the butter, garlic and Sriracha mixture over top, and toss. Let cool to handle then pull meat from the bone and roughly chop.

Place a large cast-iron or nonstick skillet over medium heat.

Butter one side of all of the slices of bread and build the sandwiches with the buttered sides facing out. Top each slice of bread with 2 slices of cheddar, about 1/4 cup of the chopped wing meat, a sprinkle of scallions, some blue cheese crumbles, and the second piece of cheddar. Top with the remaining slice of bread, buttered side up, and add to pan. Cook in batches if necessary. Cook 2-3 minutes per side, or until bread is golden brown and cheese is melted.
