I will make this again! We grilled whole thighs for two reasons - it IS summer and I can’t keep him away from the grill and I prefer using the meat’s natural juices instead of adding fat (olive oil) to boneless skinless breasts. To keep the fat and calorie count low just remove skin after cooking, before adding sauce.
I used a fresh sweet onion (including greens) instead of shallots because a previous comment said the shallots were a bit strong/bitter, so the sauce was slightly sweet and very tasty!
French bread for dipping was a wonderful suggestion. S.O.S. made from this sauce, picked chicken & French bread was a wonderful lunch the next day.
