Vegetarian Sausage Guide

DG asked about veggie sausages. I am currently addicted to Asda's own brand frozen vegetarian hotdogs, they are delish and also v diet friendly cos you boil instead of frying. I think most supermarkets stock their own brands, or if not they stock the tivall ones. We eat sosmix sausages quite often too, handy store cupboard stand-by, but nothing like 'real' sausages (and also can absorb quite a lot of oil while cooking, if you're not careful).
