Instructions

  1. Boil pasta in salted water, as directed. While pasta is cooking, spray a 2 quart casserole with nonstick spray; open cans of tuna, soup and mushrooms.
  2. Drain pasta, return to pot and add all other ingredients. Mix well and pour into casserole dish. Sprinkle cheddar cheese on top.
  3. Bake at 350F for about 30 minutes. You just need the casserole to heat through. Remove from oven when cheese has completely melted and let cool for 5 minutes before serving.
