I pretty much followed the recipe although I did follow the 1st reviewer's lead & up the amount of Dijon mustard (something I ALWAYS have on hand), & we had a great tuna casserole! Ages ago I used to make something similar when my kids were small, but that recipe is long gone, though yours is a delightful substitute! Thanks for sharing it!

This was a great tuna casserole.The celery and red pepper added color and were yummy with the tuna. The sauce was creamy and good too- I used twice the Dijon mustard for more flavor. The potato chips were fun and provided a salty crunch to the topping. I'll be making it again for sure. Thank you, Chef mariajane.
