ipsos I can understand the struggles with finding things to eat. We are only gluten free and while its not as limiting as it was initially, until I found my feet, but a lot of the cheap meal "ideas" are rubbish. Even a simple stir fry is ridiculous, no soy sauce, so have to buy tamari for €3.75 a bottle. What exactly do you avoid, maybe some of my regulars might suit you, ds and dh? Lots of gluten free meals are dairy free too. Send a pm if you like! 
My husband used to be really fussy too. He changed himself tho, it got to weaning time with ds 1, and he felt that it would be hard to tell a child to eat his vegetables when he was sitting down to his processed rubbish. So it was gradual, but gluten aside due to coeliac, he eats everything I put in front of him!
Could swing for him this evening tho, we went to a festival, and all the kids were walking around with toys a stall were selling. Dh told our boys that they could get one too. €18 it cost. Only have €10 left from my weekly spends now. I'm so annoyed with him!
Spent loads before we got there, €20 for 2 jumpers for ds 1, €2 for 2 Halloween craft kits, 90c for Christmas cards (couldn't leave them there!) €20 for new wipers for dh car, and €2.90 for a kringle candle.
