Tasty, yet simple, and easy to digest, this is my elderly Mom's favorite casserole. I adapted it from Johnny Marzetti in Jean Anderson's "The American Century Cookbook". My Mom asked me to double the mushrooms; the baby Portabella mushrooms available at Costo or Sam's are a hit in this casserole. Use low-sodium tomato sauce and Cabot's cheese to reduce the amount of sodium. Anyone else can slash my preparation time, I am "the slowest chopper in the Western Hemisphere."
