Here's a jazzed-up version of Mom's tuna casserole that's sure to be comfort food for the whole family! Jan Heshelman of Bloomfield, Indiana adds pizzazz to the traditional dish with mustard, sour cream, thyme and zucchini. "I found this recipe in a magazine," says Jan. "It is one of the few dishes with zucchini that my husband will eat."


  • 3 cups uncooked yolk-free wide noodles
  • 2 cans (6 ounces each) light water-packed tuna, drained and flaked
  • 1 cup shredded zucchini

  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon salt
  • 1 cup shredded part-skim mozzarella cheese
