Salad with Shrimp, Corn, Cilantro and Avocado

I made this the other night for John and he loved it.
1 pound shrimp
1 avocado
5 ears of corn
cilantro
1 beefsteak tomato
Romain lettuce
black pepper
vinaigrette

Boil one pound of shrimp in their shells. Then, rinse in cool water and remove shells. Boil the corn, rinse and remove kernels. Chop tomatoes, toss with lettuce, cilantro, corn, shrimp and black pepper. Dress the salad and serve with avocado on the side.
