Cajun Shrimp Salad

1 (15 ounce) can canned tomatoes, stewed - Cajun style
8 ounces shell macaroni
1 1/2 cups chopped celery
1 bunch scallions, including tops
1 1/4 pounds large shrimp
1 teaspoon Old Bay seasoning, more or less to taste

Cook macaroni according to package directions, cool.

Cook shrimp, by steaming until color turns from gray to pink. Be careful not to over-cook shrimp or it will be mushy in texture. Peel and cut shrimp into 1-inch pieces.

Chop celery into small pieces. Slice green onions. Combine all ingredients and mix. Season with more Old Bay seasoning, if desired. Chill for 1 to 2 hours before serving.

Garnish with sprigs of fresh parsley before serving.
