Preheat the grill to medium heat.

In a large bowl, combine ground beef, kosher salt, and 2 tablespoons barbecue sauce. Gently mix by hand until just combined to avoid overworking. Shape the mixture into 4 equally sized patties, slightly larger than the buns. Create a shallow divot at the center of each patty with your finger.

Lightly oil the grill grates. Place burger patties onto the grill and cook for several minutes per side. When flipping the burgers, add pineapple slices to the grill and cook for 1–2 minutes per side until tender and charred.
04 -
Cook burgers to an internal temperature of 74°C for well done, or to preferred doneness. Remove from the grill and rest momentarily.
05 -
If preferred, toast the brioche buns cut-side down on the grill until lightly golden.
06 -
Spread mayonnaise onto the cut sides of each bun, or use a blend of mayonnaise and barbecue sauce.
07 -
Place each patty onto a bun base. Top with a grilled pineapple slice, 1–2 slices of bacon, and drizzle with additional barbecue sauce. Cap with bun tops and serve immediately.
