Fairy I think you're being unnecessarily critical - it's not about aspiring to her lifestyle, I don't think anyone could read a post like "hunger hurts" and think that they wanted a bit of that themselves! What is inspirational about Jack is that she made such an effort to keep cooking healthy food with veggies etc in it even though she didn't have a lot of money. So many people claim that healthy food is too expensive etc. Also, even though I am not living on £10 a week I really, really need to economize, pay off debts and start saving for my future, so yes, I will copy her cheap and healthy recipes and I see nothing wrong with that.
Rather than stand around lamenting the state of things in this country and criticizing others I prefer to get on with life and start solving the issues I face, using whatever resources I can find to do so.
When she's eating a jam/lemon curd sandwich for lunch, she's on her LBL project: living below the line at £5 a week. She's incredibly versatile.
Also, re chickpeas. With a slow cooker you don't need to soak. I chuck them in in the morning with onions, garlic, tomatoes, water, frozen veg and anything else I can think of - plus seasoning and herbs or spices. We come home to a gorgeous stewy thing. Only dd and I will eat it, mind, but it's lush.
