01 - Heat a large skillet over medium-high heat. Add the ground beef, breaking it apart with a wooden spoon. Season with salt, pepper, garlic powder, and onion powder. Cook for 8 to 10 minutes until evenly browned and no pink remains. Drain 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. Set aside on a prep board or in bowls.
03 - Divide the chopped romaine lettuce evenly among four serving bowls to create a crisp, fresh foundation.
04 - Spoon the seasoned, cooked ground beef over the lettuce in each bowl while still hot.
05 - Top each bowl with diced tomatoes, sliced red onion, chopped pickle, sliced avocado, and shredded cheddar cheese, distributing everything evenly.
06 - Finish each bowl with a drizzle of 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 warm.
