From grilled cheese to PB and J, Sandwich King Jeff Mauro has proven himself the master of reinvention with his surprising new takes on classic sandwiches. Here are some of his most-popular creations.

Jeff's showstopping sandwich is unlike any grilled cheese you've ever had. A helping of creamy mac and cheese makes up the ultra-cheesy filling, and crispy bacon adds crunch.

When making meatloaf, Jeff says the key to juicy texture is to use 1 egg for every pound of meat you have. Once cooked, slice it and serve on potato rolls with crispy onions plus bread-and-butter pickles — you can't go wrong.

Jeff recommends using chicken thighs for his spicy Buffalo Chicken Subs — the dark meat lends extra flavor and juiciness. For an over-the-top lunch, serve the broiled, caramelized chicken on French bread with blue cheese crumbles, fresh veggies and Homemade Ranch Dressing.
