OH is a Vegetarian, has been for 17 years, doesn't eat any meat or fish, gellatine, or wear leather so is pretty devout. It has got easier even over the past 12 months for us to have the same meal, just his is the Quorn substitute as the range has widened so much. I eat a lot less meat than I used to too as with a lot of it, you can't tell the difference.
He is so excited as he can now have fish finger sarnies, pork pies, scotch eggs, steak and ale pie, meatball subs, loads of stuff he couldn't a wee while ago.
He still can't eat a lot of sweets or cerals and it astounds me in this day and age, they use gellatine in as many products as they do but it is getting better. It just means when we do find a bag of sweetie snakes that he can eat, we stock up on them!!
As has been said, just make sure you take good vitamins if you do go ahead with it xxx
