You can of course substitute the chicken for Quorn chicken pieces, which are equally delicious and nutritious
Which has to be true as chicken tastes mainly of nothing at all that you'd notice. I'm a lamb shanks fan myself. Yummy.
I understand what you're saying, but you're buying the wrong chicken if it's tasteless! Shop around a few butchers, mine come from Packington Poultry in Tamworth and they have some serious flavour.
