Directions
In a large bowl, mix ground beef with 2 tbsp. red onion. Add black pepper, steak seasoning, garlic salt, and chipotle purée; mix until well blended.
Divide meat in 6 balls (3 a bit bigger and 3 smaller ones), and using a burger press, lay the bigger ones in one at a time, and form the patty. Press down in the middles to form a well.
Add 1 tbsp. of onions per patty in the well before adding the same amount of red peppers and mushrooms. Add a few dashes of hot sauce, barbecue sauce of your choice and grated cheese; season with freshly ground black pepper.
With the 3 remaining small balls, form patties and place one on top of each of the stuffed patties, forming a burger and sealing the edges.
Place them on a plate, cover with plastic wrap and transfer to the refrigerator for at least 1 hour.
Preheat barbecue to 500ºF.
Place burgers on the hot grill, close the lid and cook about 7 minutes per side. After flipping, wait about 4 minutes before adding the barbecue sauce.
