Hi ilovemydogandmrobama!
Yes I have loads of suggestions, as a long term vegan I've tried a few.
My favourites are either 'cheese' slices from Tofutti (Morrisons now sell this type made by by 'Pure', they also sell a 'cheese' spread by 'Pure' as well). These are the easy to find.
Also there is a delicious philly type non-dairy cheese spread I use on sandwiches in summer, you can have a herb variety too. (I forget who makes this)
Also If you like Parmisan,there is a non-dairy 'Parmizano' by 'Life free from' I think we found this in the 'free from' section of Morrisons as well.
Remember you can also buy non-dairy yoghurts from Alpro & I think Benecol do one too. And not forgetting Plamil non-dairy mayonaise!
Also by the way, try non-dairy 'Swedish Glace' ice-cream, its amazzzing!
For further advice, contact the vegan society who can really help you with this & other product advice here
Sorry to go so much, but there's a LOT of good products out there. You usually have a better choice from the non-chain health food shops.
Let us know how you get on!
