Preheat the oven to 350 degrees.

Pull wonton wrappers out of the fridge and let stand at room temperature for about an hour so they become more flexible. Spray both sides of 24 wonton wrappers with nonstick cooking spray and place gently into the cups of 2 muffin tins. Pop into the oven for 5-7 minutes, or until the edges start to turn lightly golden brown. They can instantly go from pale to burnt, so watch them carefully. Pull them out of the tins and let them cool on a wire rack.

Brown the ground beef and remove excess fat from the pan by absorbing it into a paper towel. Add the taco seasoning, sugar, and water. When most of the water evaporates, add the neufchatel cheese until it completely melts into the beef. Squeeze on the lime, and taste for seasoning. Add salt and pepper as needed. Feel free to add a couple dashes of hot sauce into the mixture for a kick. Keep the beef warm in a covered pot for guests to serve themselves.

Let the guests assemble their own cups by filling each one with a little lettuce. Top with a spoonful of the beef mixture. Place a small dollop of sour cream on top and garnish with the cherry tomato and cilantro. Serve with a bottle of hot sauce on the side and extra lime wedges for guests to squeeze on top. Feel free to be creative and add any additional toppings you want, such as salsa, guacamole, sliced black olives, chopped green onions, or pickled jalapeno slices.
