Skinnymixers Tuna Mornay

While this Tuna Mornay Thermomix recipe from The Healthy Mix IV doesn’t use a traditional ‘mornay sauce’, I think you will find this really delicious. It also has the added bonus of cutting down on the dirty dishes and having hidden veggies to boost the nutrition!

Tuna Mornay is one of those very polarising meals. Many of us grew up being forced to eat some sort of stodgy variation of the basic bechamel, pasta and tinned tuna recipe popularised in the 50s. 

The Skinnymixers Facebook Community has been asking for a Tuna Mornay Thermomix recipe for a few years now and I final checked it off the list as the People’s Choice recipe for The Healthy Mix IV cookbook!
