GRILLED MAC AND CHEESE WITH PULLED PORK

Steps:

• Put 6 tablespoons butter and the mayonnaise in the bowl of a stand mixer; beat with the paddle attachment until combined, scraping down the sides of the bowl as needed. Set aside.
• Spread the macaroni and cheese in an 8-inch-square baking dish to about 3/4 inch thick. Cover with plastic wrap and chill until firm, about 45 minutes. Cut the macaroni and cheese into squares that are slightly smaller than the bread slices.
• Meanwhile, melt the remaining 2 tablespoons butter in a skillet over medium heat. Add the onions and cook, stirring, until caramelized, about 20 minutes. Season with salt and pepper.
• Combine the barbecue sauce and pulled pork in a saucepan over low heat and cook until warmed through, about 5 minutes.
• Generously spread the butter-mayonnaise mixture on one side of each bread slice. Flip over half of the bread slices; layer 1 slice of cheddar, 1 macaroni-and-cheese square and another slice of cheddar on each. Top each with one-quarter of the pulled pork and caramelized onions and another slice of cheddar. Top with the remaining bread slices, buttered-side up.
• Heat a large skillet or griddle over medium-low heat. Working in batches, cook the sandwiches until the cheese melts and the bread is golden, about 5 minutes per side.
