From Walt Disney’s Mickey Mouse Cookbook (A Golden Book) I received when I was 7 and still use about once a week.
1 can (7.5 oz) tuna fish (drained)
1 can (8.75 oz) green peas (drained)
1 can (10.75 oz) condensed cream of mushroom soup
1/2 cup milk
3 cups cooked noodles
1/2 teaspoon salt
Preheat oven to 350 degrees.
Empty tuna into 1.5 quart casserole dish. With a fork, break up into small pieces.
Add cream of mushroom soup to the tuna in the casserole and stir. Stir in the milk a little at a time.
Add the peas, noodles and salt to the tuna mixture and stir everything together.
Bake for 30 minutes. Serves 4.
Angela’s notes: I add pepper with the salt. I usually top my bowl with parmesan cheese. Sometimes if I don’t have a can of peas I use 2 cups of frozen peas (after thawed of course) or peas and carrots mixed.

Seriously – thanks for posting this….I remember making it as a kid & today I had a pang of nostalgia. Hopefully it tastes as good as I remember!

I make a very similar casserole using frozen peas – I add some dried tarragon to the soup mixture, along with some other goodies, and layer the tuna & peas in between 2 layers of sliced potatoes/onions. Great comfort food & fabulous to have on hand for our business!
