The cheese cracker topping sets this tuna casserole apart from all the rest. The pasta shells and a rich cheese sauce make it a satisfying one-pot meal.

Onion and celery are the vegetables called for in the recipe, but feel free to change them up to suit your taste. Green onions, diced frozen carrots (cooked), mushrooms, and bell pepper are just a few of the possibilities.

  • 6 tablespoons butter
  • 1 1/2 cups diced celery
  • 1 1/2 cups diced onion
