Mix lettuce, tomatoes and cheese in a medium bowl until well combined. Divide evenly among the Scoops (about 1 1/2 tsp per Scoop)

Stir 2 tsp water into the taco seasoning in a small bowl until it has no lumps. Set aside.

Preheat a small nonstick skillet over medium-high heat. Add beef. Use a wooden spoon to coarsely crumble the meat as it cooks. When the beef is no longer pink, after 1 or 2 min, stir in the seasoning mixture. When no liquid remains, after about 1 minute, remove from heat.

Divide the meat evenly among the Scoops, atop the lettuce mixture (about 1 tsp in each). Dollop the top of each with taco sauce. Serve immediately.
