This is my own concoction, but I like it so I thought I'd share.

Put water to boil in a 6 qt. pan.  Then boil egg noodles per directions. (I prefer the medium rather than wide.)
After the noodles are cooked & drained put them back in the pan on low heat.  Add:

6 slices velveeta cheese
2 cans cream of mushroom soup (or chicken, or celery)
2 5 oz. cans drained tuna
a handful or 2 of frozen peas

Add a little milk to the mixture because it can get too dry & stir all the ingredients together.  Heat everything up & serve.
