Finely chop the water chestnuts and drain any excess liquid before adding them to the filling.

In a large bowl, mix the thawed and well-drained spinach with softened cream cheese, mayonnaise, sour cream, and the Knorr Vegetable Recipe Mix until smooth and evenly combined.

Gently fold the chopped water chestnuts and bacon pieces into the spinach-cream mixture so they are evenly distributed.

Spread a quarter of the mixture across each spinach flour tortilla in an even layer, then roll each tortilla tightly and wrap in plastic wrap snugly.

Place the wrapped rolls in the refrigerator and chill for at least one hour.

Unwrap and slice each roll into bite-sized pinwheels using a sharp serrated knife.
