01 - Heat a large skillet over medium-high heat. Add the ground beef and break it apart with a spoon. Season with salt, pepper, garlic powder, and onion powder. Cook for 8 to 10 minutes until fully browned and cooked through. Drain any excess fat if necessary.
02 - While the beef cooks, chop the romaine lettuce, dice the tomatoes, thinly slice the red onion, chop the dill pickle, and slice the avocado.
03 - Divide the chopped romaine lettuce evenly among four serving bowls to create a fresh, crisp base.
04 - Spoon the hot seasoned ground beef over the lettuce in each bowl.
05 - Top each bowl with diced tomatoes, sliced red onion, chopped pickle, sliced avocado, and shredded cheddar cheese.
06 - Drizzle burger sauce or mayonnaise, ketchup, and yellow mustard over each bowl to taste.
07 - Sprinkle with sesame seeds and fresh chives if desired. Serve immediately while the beef is still warm.
