Be wary of what size chicken breasts you use or you may end up with what we got - tough on the outside and raw in the middle despite cooking it a tiny bit longer than the directions state. To our fault, we didn't think this through when purchasing the chicken. The recipe calls for 4 chicken breasts (about 1 lb) but all we could find in the store were packs of 3 which weighed over 1 lbs already (about .5 lbs per breast). The flavor itself wasn't all that spectacular either. The rosemary predominated the flavor and everything else was masked by it.
Sad to say that I don't think we'll be making it again.
