Everyone's out at some graduation malarky, so I'm cooking for myself.

Right, all I need to know is something to do with these sauces in jars.

I'm cooking some chicken breasts to have with this Uncle Ben's Rogan Josh sauce.

What I want to know is, do I boil the sauce in a pan on its own, or do I cut the chicken up when its cooked, and put it all in the saucepan together?

The jar is useless for advice, and just has friendly 'advice' on it.

THANKYOU!
