This is a wonderful side dish salad or can be served as a light main entree.
Cook pasta according to package directions. Rinse with cold water, drain and toss with a small amount of olive oil to prevent sticking. Once the pasta is cool, toss with 1 lb shrimp and remaining ingredients, excluding the endive and 1/4 lb of shrimp for garnish. Taste and add a bit more vinegar or salt and pepper to your liking. Place endive spears on plate and spoon a generous helping of pasta on top. Pile the extra shrimp on top for a pretty presentation. Serves 3-4.
