An adult should cook and drain the pasta, open and drain the tuna cans, melt the butter, handle the hot baking dish, and place the casserole in and out of the oven.
Stir 1/2 cup sour cream or plain Greek yogurt into the sauce before adding the tuna and pasta. Add 1-2 tablespoons of milk if the mixture seems too thick.
