In a small mixing bowl, whisk together the Greek yogurt, avocado oil mayonnaise, yellow mustard, pickle juice, and smoked paprika until smooth to create the special sauce.
Heat a non-stick skillet over medium-high heat and add the ground beef, breaking it into small crumbles with a spatula.
Season the beef with sea salt, black pepper, garlic powder, and onion powder, and continue cooking until the meat is browned and fully cooked through.
While the beef is browning, chop the romaine lettuce into bite-sized pieces, halve the cherry tomatoes, finely dice the red onion, and slice the dill pickles.
Assemble the bowl by placing the crisp romaine lettuce at the base, then layering the cooked beef, tomatoes, onion, and pickles on top.
Shred the cheddar cheese over the warm beef to allow it to melt slightly, then drizzle the entire bowl with the prepared special sauce and garnish with sesame seeds.
