1 loaf thin bread (trimmed and cubed)
1/2 c. finely chopped onion (start with 1/4 c.)
1 c. finely chopped celery (more if you like)
4 hard cooked eggs, chopped
2 cans drained shrimp or crab or 1 of each
3 c. mayonnaise (start with 2 c. and add more if needed)

Mix and store overnight in refrigerator to mellow.

Some onion is so strong it takes over. Check next day for flavor to see if it needs more. Probably 1/3 cup should be about right. If it is too dry add another cup of mayonnaise.
