This is an adapted recipe of Madhur Jafreys. I have had great success with making this recipe for guests. People are always asking for this recipe as they see how quickly I get dinner together and they love how it tastes. I have used ground turkey as a sub for the ground chicken. Also I have used cubed chicken breasts if I don't have ground on hand. I once used leftover Tzatziki sauce and used that in lieu of the yogurt or sour cream and it was also good. The curry powder I use is the Sweet Curry I buy from penzeys.com. The recipe is flexible if you want to add 1 cup of cooked/cubed potatoes and/or 1 Cup of frozen peas at the step where you add the tomatoes.
