Jeff Mauro's 9 Favorite Sandwiches Slideshow

While hot dogs have become popular in places like Los Angeles and New York, a seemingly unlikely source is Sonora Grill's hot dog, a $4 bacon-wrapped hot dog, fried Mexican-style on a griddle and placed in a bakery bun then topped with chipotle sauce, cilantro, and onions.

When Mauro is craving a sandwich in his hometown of Chicago, he heads to Johnnie's Beef for the hearty and meaty Italian beef sandwich.

"My favorite sandwich in the world," said Mauro of the hand-cut pastrami and Rye at Langer's Deli in Los Angeles. The pastrami is sugar-cured and seasoned and then slowly smoked.

The "Caprese Sub" at Conte Di Savoia is the go-to sandwich. It's piled high with fresh mozzarella and sun-dried tomatoes, and Mauro always orders this sandwich.

Mauro makes it a point to make a pit stop at Schoop's for its hamburgers, which are griddled flat with crispy, lacy edges. Mauro keeps it simple and gets his with American cheese at the hamburger chain that has been griddling hamburgers since 1948.

Mauro enjoys the fried meatball sub at Danny's Deli, which features a half-pound of smashed and grilled meatball patties sandwiched between ciabatta slices.

"I'm a simple man," said Mauro, and his order of the humble pastrami sandwich at Second Avenue Deli is proof. It's a no-frills sandwich, and many of Mauro's favorite sandwiches only include three to five ingredients.

Named for the Sandwich King himself, it's fitting that Mauro orders his own sandwich, which was also featured on Sandwich King. The sandwich, which is on the lunch menu at Gibsons Bar & Steakhouse, is made with hand-cut, thinly sliced USDA Prime Angus rib-eye topped with sautéed spinach, crispy garlic chips, and dressing.

When he is in Cleveland, Jeff Mauro orders the corned beef sandwich at Dannys Deli.
