I prefer to use chicken thigh meat which I find more flavorful, but you could also use chicken breast meat but cook it for a shorter time. (easynaturalfood.com)
I made this with both thighs and breasts and definitely preferred the whole pieces of thigh meat. (popularpaleo.com)
Since the dark thigh meat needs longer to cook than the white breast meat, it's helpful to chill the turkey breasts with ice packs before roasting. (greatist.com)
