Use shredded rotisserie chicken in place of the shrimp, if you'd prefer. For quick suppers, keep a bag of cooked, peeled, and deveined shrimp in the freezer. Set the shrimp in a colander and rinse with cool water to thaw quickly.

How to Make It
Bring water to a boil in a large saucepan. Add shrimp; cook 2 minutes or until done. Drain and rinse with cold water. Place shrimp in a bowl; cover and chill.

Spoon 1 tablespoon dressing over shrimp; toss to combine. Add shrimp mixture and remaining dressing to lettuce mixture; toss gently to coat. Spoon about 2 3/4 cups salad onto each of 4 plates.
