I'm also vegan - and I've been 5:2ing for almost two years!
I started off with 3 small meals on a fast day, but very quickly went on to fasting all day and eating a <600 calorie dinner (I'm a bloke).
I have my own blog, and you've inspired me to collate all my 5:2 vegan dishes into one post.
Have a look around the blog, I'm sure you'll find something to suit you. But I'd also urge you to come and join the main thread - we've had loads of new posters since the new year, and you'd be made very welcome.
I am also a vegan who started 5:2 at the beginning of the year. 7 FDs complete so far. I spend a lot of time on the main thread on FDs to keep me going, it's been invaluable to have a support group.
I tend to have a coffee around 10:00 with a dash of soy milk, crudites and shop-bought salsa around 13:00, then in the evening I have a small bowl of homemade soup, or there are some good shop bought ones, with a side of cabbage, or an innocent vegpot if I don't have much in the house. I also have some teas throughout the day, some with soy milk and some fruit teas.
I've found B&W's website really good, it has recently inspired me to start experimenting with some simple breads :-)
