Heat a non-stick, medium size sauté pan over medium-high heat; on the stove top. Place raw ground beef into pan and brown (approximately 5 minutes); then drain. Place drained cooked beef back into the non-stick sauté pan, add taco seasoning and water. Continue to cook until water is gone and beef is thoroughly mixed with seasoning. Reserve warm.
Fill each tortilla with approximately ¼ cup of reserved taco meat, top with 1 tablespoon of lettuce, 1 tablespoon of pico de gallo and 1 tablespoon of shredded cheese.
