My mum used to make Tuna Mornay for us all the time as children. I remember when she began to make this for us, it wasn’t long after she purchased her first microwave oven. She went and had lessons at the local TAFE on how to use it and came home with a folder full of microwave recipes. Sounds similar to what the thermomix is today, newest greatest gadget and you can go and get lessons. Mum always served the mornay on toast and as per the recipe suggested she served it with crushed potato chips.
Looking at other Tuna Mornay recipes, traditionally it’s not served with potato chips, but to me it just isn’t the same without them, I know it’s not a healthy options…. but I do continue to serve them with crushed BBQ chips on top. I also like to add in small spiral pasta, makes the dish go further, my recipe usually makes enough so I can have left overs the next day for lunch!
