Heck with bread crumbs. Lighly crushed potato chips!Tuna casserole is great.
Turn on oven to 375 degrees.
In a large pot, melt a 5 inch block of Velveeta cheese add 3 cans tuna (NOT albacore) and 3 cans mushroom soup with 1/2 can of milk. and 1 can sweet peas, drained. While you are cooking that mixture, boil 1 bag of egg noodles.
When cooked to your taste, drain the noodles and put back into the pot you boiled them in.
When cheese/soup/tuna mix is melted together at a very gentle boil. dump into the pot of noodles and mix thoroughly
(You can add shredded cheddar if you really like it cheesy)
Pour the noodles etc into a suitable sized baking pan, sprinkle bread crumbs and shredded cheese on top and cook in the oven for 30-40 minutes . Look in on it after 30 minutes . A crispy but not burnt top is what you're looking for.
When done, remove from oven and let it sit for 5 minutes then plate it and enjoy!
