I am in the same boat and have not found anything as good. I use a soya spread' by Pure but it is not the same. If you can get to a Wholefoods then stock up and even bring a cooler bag to take frozen foods home as they have some nice veg burgers etc. Online, I sometimes use Goodness Direct to get hold of stuff that I can't get in local supermarkets or health shops, and they have some non dairy cheeses but again, the choice is nothing like in the USA. They get the weather AND the good food!
I know what you mean, When in the US I loved earth balance. I am pretty much stuck with the pure spread. I live near a wholefoods and would be lost without it. I also use local health food shops, Holland and Barrett and another wholefood type shop near me. I can usually get all the "junky" vegan things like burgers and sasuages for the little vegan in my life too :) But the choice is just not t he same at all. ALthough we recently discovered the really nice Bessant and Drurys Coconut Ice cream Sooooo good. There is a constant fight in our house when I get some in for a treat.
I lived in central london before coming to university in St Andrews....If you think your food choices are limited, imagine mine now!
In London I lived within a ten minute walk from soho and would usually be able to get most of my groceries from either whole foods or china town. In China town things like dried seaweed etc are far far cheaper and in huge quantities.
My family is originally Greek so I tended to buy anything lentil/grain/tea/herb/ related at a Greek or Turkish food store.
Now that I live in the middle of nowhere I buy Pure spread (but I guess the difference is that that's the only thing I've ever eaten at home so i like the taste), Alpro soya milk and things like jusrol ready made pastry from Tesco. Also, random fact, ginger nuts are usually always vegan - don't ask me why....I also buy Nakd bars, corn cakes, rice cakes and dried fruit from Tesco or Morrisons too.
When I go home whole foods is my meca...I literally spend hours in there. I get all my frozen foods and special things like vegan marshmallows and booja booja chocs.
The best advice I could probably give is to keep it simple and not rely on substitutes. You can buy grains, lentils and beans from even the most basic places. The subs can be tasty but I very rarely eat them because they aren't nourishing. Also every year when its pumpkin season I prepare my own pumpkin puree and freeze it. It's cheaper than buying the tinned stuff and far better for you.
I live in cornwall uk, i use alot of redwood foods and they are really yummy! i try to stay of to much soya as its quite bad for you , redwood do alot of non soya meals using chickpeas instead. Holland and Barret are really good stockest. :)
I use the Pure Sunflower spread and have done for years - even before I was vegan. The soya version is not so good though. Bute Island cream cheese is very good and now Tesco have a "free from" range which includes a rebranded Bute Island cream cheese range and also some hard cheeses that are really the best I've had in this country - especially for slicing, grating and melting. I now live in a very small place in Scotland where the word vegan is not known so I know where you're coming from Katerina. There is a WFM now in Glasgow but it's very small and their vegan range is not large or promoted like it is in say the New York stores which are wonderful. Mostly I cook everything from scratch and try to stay away from the processed convenience foods as much as possible but every so often I want to eat Linda McCartney Country pies or her vegan sausages.
