Add ground turkey to a skillet. Cook over medium heat for 8 minutes until browned. Add 1/3 cup water, taco seasoning, and salt (if not already an ingredient in the seasoning). Allow to cook for 3 minutes more. Remove from heat.
Double each lettuce leaf so the top fits into the second and you have 6 doubled leaves altogether. Spoon in the meat mixture. Add cherry tomatoes and avocado pieces. Top each with salsa.
