Easy then. Fry onions and garlic and any other veg you may have ie peppers in butter add as much curry powder as you want and your raw chicken, fry until chicken is browned then add your liquid - chicken stock or coconut milk or tinned tomatoes, whatever you have in and either transfer to a lidded casserole and put in the oven, put in a slow cooker, or put a lid on the fry pan and cook until chicken is cooked . half an hour before its finished cooking you could add various finishes depending on what your liquid is - tomato based you could add some frozen spinach, green beans and or chopped fresh herbs, coconut based some chopped apricots or even better a mashed banana. If the liquid is too thick wither reduce with lid off or add some chicken gravy granules or corn flour. I know this is basic, but needs must and it does make a decent curry. Basically if you have the curry powder you can follow almost any recipe that required 10 spice ingredients as they are already in the premixed curry powder.
