Smash Burgers

While potatoes cook, heat a large non-stick pan over medium heat. When hot, add 1/2 tbsp oil (dbl for 4ppl), then onions. Cook, stirring often, until slightly softened, 3-4 min. Add 1/2 tsp sugar (dbl for 4ppl) and season with salt. Cook, stirring occasionally, until dark golden-brown, 3-4 min.

While onions cook, cut pickles into 1/4-inch pieces, reserving pickle juice. Roughly chop the parsley. Combine beef with half the mustard, 1/4 tsp salt and 1/4 tsp pepper (dbl both for 4ppl) in a medium bowl. Form beef mixture into two 4-inch wide burger patties (four patties for 4ppl). Set aside. When onions are dark golden-brown, remove pan from heat. Transfer onions to a small bowl. Set aside. Carefully wipe pan clean.

Heat the same pan over medium-high heat. When hot, add patties to the dry pan. Using the back of a spatula, gently press down each patty. Cook, until bottoms are golden-brown, 3-4 min. Flip patties and cook, until the other side is golden-brown and patties are cooked through, 3-4 min.**

While patties cook, stir together half the pickles, ketchup and 1 tbsp mayo (dbl for 4ppl) in another small bowl. Set aside. (NOTE: This is your tangy mayo!) When potatoes are fork-tender, drain and return to the same pot, off heat. Add parsley, pickle juice, remaining pickles, remaining mayo and remaining mustard. Season with pepper and gently stir to coat.
