    This is an easy tuna casserole – just like I remember it from childhood. I had to leave the celery out due to my DIL who doesn’t like celery. But it would have even better with it. I think it would also be really good as an “after turkey day” casserole using leftover turkey. Thanks for sharing this recipe.

    • I’m so glad this casserole brought back memories for you. That’s one thing I love about recipes – that you can modify them to meet the dietary needs of your family. That’s a good idea to put turkey in it after Thanksgiving. Thanks for commenting.
