I find the meats really tricky too
I eat alot of (tasty) meat patties of mixed chicken/veal/beef mince mixed up with finely shopped shallots, diced carrot, celery, parsley, leek, 1 garlic clove, cooked rice and egg replacer. I thne coat it all really well in rice crumbs and pan fry. That way the crumbs get browned and not the meat.
I also eat roast lamb and don't eat the juices or the yummy charred outside bits. Same for roast chicken. I roast all sorts of cuts so they are just brown/cooked on the outside but not charred KWIM. It is recommended to add water to the pan - yuck! the meat goes grey
Also make simple stir fries, just make sure that the meat doesn't get browned and more cooks in the juices of the stock in the stir fry.
I make poached homemade sausages in stock, they are tasty too without browning the meat. Just can't eat aged scotch fillet anymore or anything with a yummy BBQ flavour
Fish is easy, fish can be crumbed, steamed with some shallots for flavour or pan fried quickly. I also eat a fair bit of calamari - shallow fried in potato starch batter - it goes nice and crispy, and also make veal spring rolls - they can be pan fried without worrying about the meat part. Fresh oysters are allowed too.
Buying meats is easy now as I go to same butchers that I trust, they know me and my wierd diet
But I have fond that most butchers when questioned all comply to the rules for hanging, freshness and storage, most don't put preservatives in their mince either. Its just the supermarket meats that don't comply.
