Butter chicken - use a jar of sauce and a slow cooker.

Slice chicken and add sauce, stir well.  It will be done in 2 hours on high or 4 hours on low.  I used sauce from Costco.

Add twice the amount of water for rice (eg 250mL rice + 500 mL water) read the rice package first, some vary.

 Bring rice to the boil, then simmer, lid on, until water disappears and holes appear.
