Cut tubes of calamari into 1-inch rings and cut the tentacles in half. In a large pot bring water and 2 tablespoons of salt to a boil. Carefully place the calamari in the pot. Cook the calamari until tender, about 2 minutes. Be sure not to overcook.
Strain the calamari and place in a mixing bowl. Add all of the ingredients and mix well. Add salt and pepper, to taste. Serve the calamari cold.
