This tuna casserole is a delicious break from the ordinary. My husband and I love tuna casserole but I wanted to spice it up a little. Instead of just the usual mixed vegetables and cheddar cheese I decided to add Rotel with green chilies and cubed Velveeta cheese. We couldn't believe how delicious it was with just a little kick from the Rotel and the creaminess of the Velveeta. I hope you'll agree.
