Uniquely Delicious Tuna Casserole

Robin Lieneke


This tuna casserole is completely unique. You have never had a tuna casserole like it. No pasta and no peas. Everyone who trys it can't believe how delicious it is. Most say it is the best they've ever had. When I give people the ingredients they are amazed. Super easy to fix too.
