This is one of my family's favorites! We've been making it since I found it in one of the weeklies. I've made it for family and company and everyone loves it.
One thing I do is to cut each breast into 3-4 pieces depending on its size. This helps the marinade to permeate the chicken better.
I've made this on top of the stove (dump chicken and marinade into a pan), in the oven (chicken & marinade), broiled and all the grill. Any way you cook it, it comes out great!
