Italian Tuna Casserole

My mom was visiting and I wanted to make a delicious & healthy casserole for dinner one night so I decided to make this Italian Tuna Casserole.

A little tuna, pasta, spinach, cheese and seasoning. How can it go wrong? Besides burning the onions and garlic, this recipe is pretty simple to make, even for beginners.

This recipe does require quite a few ingredients, but don't let that distract you. This recipe is pretty simple to make and doesn't require any special skills to make. Most of the ingredients needed are pretty common and you should already have most of them on-hand except maybe the spinach.

I try to keep at least one frozen package of spinach in the freezer at all times but since I don't use spinach that often, I sometimes forget to replenish the freezer.

An alternative to using chicken broth is Better Than Bouillon. I often use it when I don't have broth on hand.
