In a small mixing bowl, whisk together the non-fat Greek yogurt, yellow mustard, dill pickle relish, and smoked paprika until smooth to create the special sauce.
Place a non-stick skillet over medium-high heat and add the ground beef, breaking it into small crumbles with a wooden spoon or spatula.
Season the beef with the sea salt, black pepper, garlic powder, and onion powder, and continue cooking until the meat is browned and fully cooked through.
While the beef cooks, finely shred the romaine lettuce and dice the white onion and dill pickles into small pieces.
Build the bowl by placing the shredded romaine lettuce at the base, followed by the warm, seasoned ground beef.
Top the beef with the diced onions and pickles for a fresh, sharp contrast to the savory meat.
Drizzle the prepared Greek yogurt special sauce generously over the entire bowl.
Finish by sprinkling the sesame seeds over the top to provide a nutty crunch that mimics the flavor of a traditional bun.
