It's easy and getting stuff like iron and protein is no problem at all. We overdo protein in the West anyway

I don't usually supplement iron except when pg and even then only sometimes. If you have a balanced diet then you'll get heaps from what you're eating....just about everything has iron in it, just some sources are better than others and vegetarians rely on non-haem sources rather than haem iron (which yo get from meat). But if you continue to eat dairy and eggs then I would be suprised if you needed to supplement. A good start would be to get your Dr to run a set of bloods so you know where you stand to start with

B12 is the other thing you need to keep an eye on but again, unless you're intending to become vegan then you'll get the minutae you need from dairy and eggs.

As for cutting it out, um...just cut it out lol. you do need to think outside the meat and 3 vege thing though. there's heaps of meat replacements (vege sausages, not-bacon etc) if that's your bag or you can go the whole hog hehe and just start learning how to use pulses and legumes etc. We are a vegetarian family and don't really eat much of the latter....but I love stuff like salsa bean nachos, hummus on toast, vege sausages in casseroles...etc etc.

I second that fab cook book Meals Without Meat. It's easy peasy stuff, not daunting at all.

Um can't help you with the issue of cooking it for DH cos I just don't...so my DF is vege by default lol.

But feel free to ask me any ?? cos I'd be happy to help
