As promised, here is my recipe for dairy free fish pie. Feel free to adapt however you want, just make sure that you choose good quality fish for the pie.
I quite like to cook, so I enjoy making these dishes when T is having his nap, but I understand that lots of people find cooking a chore! I try to maximise the number of dishes I can make at the same time, and freeze as much as I can to give myself more free time.
I made this dish, potato and spinach cakes and butternut squash "chips" all at the same time, and it took under an hour to do.
