Brown ground beef in a pan with onion powder, salt and pepper.
While the meat is browning, chop up your lettuce, red onion, and pickle spear.
Mix all the ingredients for the Big Mac Sauce: Greek yogurt, ketchup, mustard, and pickle juice.
Weigh out your ground beef according to your macros and lay on half a head of chopped iceberg lettuce.
Lay the rest of the toppings on top of the meat and drizzle ample Big Mac Sauce over the top.
Toss everything together and enjoy.
