Tuna Noodle Casserole

When I was a nanny in New York, another nanny named Shannon gave me this recipe. It is the best!

Cook 3 cups medium noodles: drain.
Combine noodles with:
1 can tuna drained
1 cup sliced celery
1/4 cup chopped green pepper
1/3 cup chopped onion
1/2 cup mayonnaise
1/2 tsp. salt
Combine and heat through:
1 can cream of celery soup
1/2 cup milk
Add:
1 cup shredded cheddar cheese
Heat and stir til cheese melts. Add to noodle mixture. Turn into 2 quart casserole dish. Bake uncovered at 350 for 20 minutes.
