One for the guinea pig owners, this. You need wonder no more 
DD1 has taken one for the team so to speak. Well it was more of a dare, "shall I eat it Mum" She should know after 16 years that I am evil and would call her bluff, "Go on",I said'
The verdict:
They don't really taste of very much, just vaguely herby.
And the initial hard crunch disappears straight away and the nugget dissolves to a mush in the mouth.
So there you have it. DD1 has done it so you don't have to 
HTH
