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, stirring occasionally, until evenly browned and fully cooked through. Drain excess fat if needed.
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. Set everything aside.
03 - Divide the chopped romaine lettuce evenly among four serving bowls to create a crisp foundation.
04 - Spoon the hot cooked 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 beef in each bowl.
06 - Drizzle each bowl with burger sauce or mayonnaise, ketchup, and yellow mustard to taste.
07 - Sprinkle with sesame seeds and fresh chives if desired. Serve immediately while the beef is still warm.
