I made the sauce first and popped it in the fridge while I did the rest of the dish and it thickened right up. Could've added some more milk to make it runny again but didn't bother. It was delicious. Didn't add the avocado simply because I had none. This was quite a tasty dish and definitely on the healthy side...too much so for one of my children apparently but definitely one I'll whip up again
