Heat a large skillet over medium-high heat. Once hot, add ground beef and cook for about 5-7 minutes until browned, seasoning with salt and pepper halfway through.

While the beef is cooking, whisk together the mayonnaise, ketchup, mustard, garlic powder, and vinegar in a mixing bowl until smooth.

On a large serving platter, create a bed of lettuce mix and distribute the cooked ground beef over the greens, followed by cherry tomatoes and red onion slices.

Add dill pickles to the salad and drizzle the special sauce over the top. Gently toss the salad to ensure everything is coated.

Consider adding extra toppings like chopped chives, bacon bits, or jalapeños. Serve immediately while the beef is warm.
