I stocked up in Iceland a couple of weeks ago and tried everything in their new range which is both vegan and gluten free. Sadly, the interesting new products - Asian burger, tofu burger, the chicken style stuff - all contain wheat. The others are really a reformulation of the original No Bull Burgers and not all of them work that well.
Jalapeno burgers - lovely, as basically just the original burgers with a bit of a kick
Meat balls - enjoyed these, worked well in a pasta dish. Similar taste to the burgers but different texture.
Sausages - these are just a bit crap really. They're a bit on the small side and tricky to cook. Taste just like the burgers but in sausage form.
Mince - I made a perfectly nice chilli with this but I wouldn't buy it again because it's not any nicer than alternatives and is a bit of a faff to use. It comes in a massive frozen block and you have to defrost it first (hate that). Then you're supposed to fry it before the rest of the cooking but it was difficult to tell if this really did anything, it didn't brown as such. And because there is so much of it you've got to make an enormous dish. Normally when I use mince type products it's to bulk something out rather than being the main ingredient. Still, it tasted nice, but be better in a packet half the size.
