Thank you AppleJane and Cats, this is really helpful.
AppleJane the meals I usually cook are: Spag Bol, chilli con carne, chicken curry, (I also make a nice vegan curry), fish with potatoes and potatoes or rice with veg, chicken and rice and veg, a variety of pasta dishes, some of which are vegetarian, others that contain chicken.
The things that I will miss will be milk in tea and coffee - can you recommend a good vegan substitute? I can't imagine anything to be quite as good for me as milk in terms of taste, but I'm sure I'll get used to it and if not, it's a sacrifice I need to make. Also, butter on bread. I almost bought Vitalife vegan spread, but saw that it contained Palm oil which is what I don't want to buy. Do you know of a decent vegan substitute for butter to put on bread?
My daughter won't be going vegan, I've decided that she'll still eat meat, fish and dairy as she's only 4 and still growing and developing. She doesn't eat a lot of meat though and I will give her vegan meals from time to time, such as vegan curry, but she will continue to eat meat, fish and dairy until she's fully grown and then she can make up her own mind about her diet.
Cats I'll look into the Bosh books, I already get their recipes in facebook and they look delicious. I'll look at the Ella App.
