Here's how to DIY. You need: chicken thighs with bone in and skin.
A pack of nandos rub. (Or two)
Some skinny McCain oven french fries (Cook in 5 mins type) and nandos brand Peri peri salt.
I did the rub ahead. Don't add oil. I then baked in the oven for 20 mins or so and finished on bbq. Serve with the sauce in a bottle.
Cover Chips with the salt.
My teenagers pronounced to be just as good as nandos. And cost about £14 all in for 5 of us. (With leftovers)
