I got this recipe from a British friend 40 years ago. Choose any vegetables you like to add to the simple curried white sauce. Add the chicken (or shrimp, or lamb or whatever), serve over rice and you have a complete meal.
I like to make this dry mix to keep on hand in my pantry. It makes whipping up a fresh batch of ranch dressing quick and easy -- just add the mayo and buttermilk. This is an adaptation of recipe #47249
