Tried them last night - as a (veggie) burger bun. Verdict - very happy with the result. Tastier than a burger bun for sure. Doesn't taste like bread though more like a pancake but lighter. I think I may cook them a wee bit longer next time - first trial is seldom perfect.
However - very acceptable - I added a quarter teaspoon of mustard to them. You can add a lot of taste tweaks to them - herbs, garlic etc. I used the cream cheese option and their are a lot of flavoured cream cheeses too.
As Holly says in the video - a very good vehicle for the filling.
BTW these are supposed to be zero carb but in reality are probably about 1 or 2 carb.
Have uploaded the video here
if anybody has difficulty seeing it.
