01 - Heat a large skillet over medium-high heat. Add the ground beef and season with salt, pepper, smoked paprika, and garlic powder. Cook, breaking up the meat and stirring occasionally, until browned and cooked through, approximately 7–8 minutes. Drain excess fat if necessary.
02 - While the beef cooks, whisk together the mayonnaise, ketchup, mustard, pickle relish, apple cider vinegar, smoked paprika, salt, and pepper in a small bowl until well combined. Set aside until ready to serve.
03 - Distribute the chopped romaine lettuce evenly among four large serving bowls. Arrange equal portions of the cooked ground beef, cherry tomatoes, shredded cheddar cheese, red onion, pickle slices, and diced avocado on top of the lettuce.
04 - Drizzle each bowl generously with the prepared burger sauce immediately before serving. Enjoy the bowls while fresh.
