They should be honest with themselves, their inner selves really want meat! Their stuff could be made in to the right shape to fit on a bun/bap or in to a roll without looking and/or tasting like meat.
Now this reducing their intake for the sake of global warming etc???? How much processing goes on to produce the stuff? If they like to content so much, why not eat it as it comes instead of wasting time, effort and energy processing it?
I've never tried the stuff and I expect that if I did I'd probably think it was OK but it's not something I want to try.
It's life Jim, but not as WE know it.
Live long and prosper.
