Spicy Cheddar-Stuffed Burgers

For 4 burgers:

1 (7-ounce) can chipotle peppers in adobo sauce, undrained

2 lb lean ground beef

2 tsp. steak seasoning (such as Montreal Steak Seasoning)

1/2 (10-ounce) package cheddar cheese, cut into 4 thick slices (Cracker Barrel recommended)  

4 sesame seed hamburger buns

Toppings: tomato slices, red onion slices, romaine lettuce leaves, yellow mustard, mayonnaise

Process chipotle peppers in a blender until smooth. Measure 4 tsp. puree, reserving remainder for another use, if desired.
Combine 4 tsp. puree, ground beef, and steak seasoning in a large bowl until blended. (Do not overwork meat mixture.) Shape mixture into 8 (4-inch) patties; place 1 cheese slice on each of 4 patties. Top with remaining 4 patties, pressing edges to seal. Cover and chill at least 30 minutes.
Grill, covered with grill lid, over medium-high heat (350° to 400°) 7 to 8 minutes on each side or until beef is no longer pink. Serve burgers on buns with desired toppings.
