Cardiologist Nightmare Smash Burgers

Preheat your Traeger Grills Flatrock to low or medium (for crispier edges). Divide the ground beef into 8 equal portions. Place 8 slices of bacon on the grill and cook fully until crispy (or to your liking). Remove the first 8 slices of bacon from the grill to paper towels. Spread bacon fat evenly over the grill top. Place onions on the grill in 8 piles on the bacon fat. Season onions with BPS Rub and cook for 2-3 minutes. Place a ball of ground beef onto each pile of onions and smash each ball down with a spatula. Season beef with rub. Add the other 8 slices of bacon to the grill next to the burgers. Cook burgers to your liking, flipping as necessary. Add shredded cheese to the burgers and melt. Butter buns and toast them on the grill for 1-2 minutes. Remove burgers when done to rest and finish cooking the additional bacon. Slather mayo on the buns, then pile lettuce on. Add bbq sauce, cheesy beef patties, and bacon. Share with friends. These go well with cold beer.
