Before I get flamed by the Chicken Liberation Front, yes I know these will be poor lickle chickens locked in boxes and never allowed to see their mummies. TBH I don't care though, cos I'm a heartless meanie. Find me the same product cheaper, or stay out of the thread.
Anyway, Tesco value chicken fillets arew £3.20/kg, which seems rather cheap to me. Yes they are the added water/salt/sugar ones, so not as good as the more expensive stuff, but I'm buying them to bulk out a curry rather than eat in a salad.
