01 - Heat a large skillet over medium-high heat. Add the ground beef, breaking it apart with a spoon. Season with salt, pepper, garlic powder, and onion powder. Cook for 8 to 10 minutes until completely browned and cooked through, draining any excess fat if necessary.
02 - While the meat 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 equally among four serving bowls to create a crisp, leafy foundation.
04 - Spoon the hot, seasoned ground beef over the lettuce in each bowl.
05 - Layer the diced tomatoes, sliced red onion, chopped pickle, sliced avocado, and shredded cheddar cheese over the ground beef.
06 - Finish the bowls by drizzling with burger sauce or mayonnaise, ketchup, and yellow mustard according to taste.
07 - Sprinkle with sesame seeds and freshly chopped chives if desired. Serve immediately while the beef is still warm.
