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, stirring occasionally, until evenly browned and 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 aside on a tray or separate bowls for easy assembly.
03 - Divide the chopped romaine lettuce evenly among four serving bowls, creating a fresh, crisp base layer for each portion.
04 - Spoon the hot, seasoned ground beef over the lettuce in each bowl, distributing it evenly so every serving gets equal portions.
05 - Layer the diced tomatoes, sliced red onion, chopped pickle, sliced avocado, and shredded cheddar cheese over the ground beef in each bowl.
06 - Finish each bowl with a drizzle of burger sauce or mayonnaise, ketchup if desired, and yellow mustard to taste.
07 - Sprinkle sesame seeds and fresh chives over each bowl. Serve immediately while the beef is still warm.
