In a medium skillet over medium-high heat, brown the ground beef until fully cooked through, about 7-8 minutes.
Season the beef with sea salt and black pepper while cooking, then drain any excess fat and set aside to cool slightly.
In a small bowl, whisk together the Greek yogurt, yellow mustard, pickle juice, smoked paprika, and garlic powder until smooth and creamy.
Chop the romaine lettuce, halve the cherry tomatoes, finely dice the red onion, and slice the dill pickles.
Assemble the salad by placing the romaine in a large bowl, followed by the tomatoes, onions, and pickles.
Top the vegetables with the warm seasoned ground beef.
Drizzle the creamy special sauce over the entire salad and garnish with sesame seeds before serving.
