Heat a large non-stick skillet over medium heat. Cook the lean ground beef until the meat is fully cooked, breaking into small pieces as it cooks. Drain and return to the skillet.
Add the dry spices (through black pepper) and water to the cooked meat and bring to a boil. Once it's boiling, lower the heat to low and simmer uncovered for 5-8 minutes.
Chop the bottom of the butter lettuce and use as the shell. Place 1/2 cup of meat into each butter lettuce leaf and fill with the rest of the toppings you choose.
