Joan, here's the recipe that I promised. I have never tried it but my aunt
says that it is great!

Family Sized Tuna Casserole

1 1/2 tbsp veg oil
3/4 c chopped celery
9 green onions, chopped
4 1/2 tbsp flour
3 c chicken stock
not quite 1/2 tsp cayenne pepper and black pepper
1 1/2 c peas or diced carrots
1 can corn, drained
1/3 c parsley, chopped
1 egg white
4 1/2c mashed potato
3/4 c parmesan
1 1/2 tbsp bread crumbs, dried
3 cans tuna, drained

Heat oil in skillet and cook celery and onion for 1 minute. Add 1 1/2 tbsp
water. Cover and cook on med-low for 4 minutes.
Sprinkle with flour and cook 1 minute; slowly add chicken stock, cayenne and
pepper. Cook until thickened.
Stir in peas, corn and parsley. Remove from heat and stir in tuna. Pour
mixture into a 10x13 baking dish. Lightly beat egg white; mix into potato and
parmesan. Spread over mix and top with bread crumbs.
*This recipe may also be halved and put into a 8x8 pan.

My aunt's hint: She adds a few drops of hot sauce into the chicken stock.

Enjoy!
