Step 1

In a very large pot bring 4 quarts water to boil in large pot. Add 1 tablespoon salt and pasta. Cook until soft, about 13 - 15 minutes (you don't want al dente pasta for this). Drain pasta and set aside.

Step 2

Meanwhile in a large bowl combine onions, crab, peas, celery, eggs, salt and pepper. Mix in the mayonnaise.

Step 3

Gently stir in the cooked and drained macaroni.

Step 4

Can, and should, be made at least 4 hours in advance and preferably up to 1 day for the flavors to marry. Cover and refrigerate. Serve sprinkled with the chopped green onion.
