Tuna Noodle Casserole with a Kick

This is a combination of my dad's cheese sauce, pasta, frozen peas, and a special ingredient.

*Prepare hot water for 4 cups of pasta. Tonight we used vegetable pureed-colored Wacky Mac.
* Obtain 4 tablespoons butter for cheese sauce. Put in saucepan.
* When water is boiling, add pasta.
* Shred a good amount of cheddar cheese for the sauce into a dish. Set aside for later.
* Heat butter. Add equal amount of flour. Add milk. Stir. If sauce is too thick, thin with milk. When sauce boils, it thickens due to some chemical reaction that my father couldn't explain, and I never learned in Organic Chemistry. Throw in desired amounts of salt, pepper, dried onion bits.
* A few minutes before the pasta is done cooking, add frozen peas to the pasta pot.
* Continue stirring the white sauce. Add shredded cheese. Stir.
* Strain pasta/peas and put in a casserole dish. Add white sauce. Stir.
* Add 1 can tuna (or more) to the casserole. Cover and bake about 20 minutes.
* Before serving, add Cholula hot sauce. (It is kosher; the hescher is hard to see at first glance).
