For Smashed Aloha Burgers
1 Add meat to a bowl or tray and pat very dry with paper towel.
2 Divide mixture into 8 1/4lbs-portions and form into large meat balls. Season the top of each with kosher salt and black pepper.
3 Preheat a grill or cast-iron grill pan over med-high heat. When the pan is hot, raise the heat to high. Working in batches, add meat and use a large, metal, off-set spatula to smash the burgers down.
4 Baste each burger with a bit of the New Primal marinade and season with salt and pepper. Cook 3 minutes and flip. Baste the cooked side of the burgers with more marinade.
5 Flip once more and cook additional 30 seconds to caramelize the top coat of marinade.
6 Transfer cooked burgers to a tray. Add sliced pineapples to the grill pan, lower heat to med-high, and cook 3-4 minutes per side or until grill marks appear.
7 Assemble burgers on an iceberg lettuce bun. Top with grilled pineapple, chipotle mayo, diced onion and a drizzle of the marinade.
