Hearty Tuna Mornay

How about something which is super filling and in one pot?
I have served this at parties and it always ends up empty! ~ now that is saying something.
The adding of the milk to the flour to make the roux is a bit touchy feely. You have to use your best judgement as to what the best consistency is for you. I prefer it to be quite thick like white sauce but you may prefer thinner?
To anyone who has never made the roux mix before (butter, flour, milk) you must ensure that when you add the flour to the butter/onion mix that the flour gets stirred for the minute indicated to 'cook' it. Otherwise the mix will taste 'powdery/floury'.
Enjoy!
