These are two blogs that I often read.
I find David Lebovitz's blog interesting - he's an American but now lives in Paris - he used to be a pastry chef and now is a food blogger/writer. I don't really do many of the recipes featured in the blog but it's good for ideas and I find it an entertaining read.

I came across Jack Monroe's blog via the Guardian website. Her recipes are aimed for people on a tight budget so I think it's a useful blog for people who are watching the pennies, students etc and although it's not exclusively vegetarian I think there's quite a lot of good ideas for veggies. Again I haven't tried a lot of her recipes but I get ideas from the blog. She has an interesting back story because she had to devise some of these recipes because at one point in her life she herself was on the bread line. Anyway I think she's very interesting and anyone who stands up to Richard Littlejohn is alright in my book.
