4 Meyer lemons, 2 zested and juiced and 2 halved
1 cup Dijon mustard
2 tablespoons finely chopped rosemary leaves
1 teaspoon crushed red pepper flakes
2 (3-pound) chickens, backbone removed and split in 1/2
Extra-virgin olive oil
During the cooking time it is a great idea to close the grill to allow the heat to cook from all directions. If grilling indoors, the chicken can be transferred to a preheated 375 degree F oven to finish cooking once the grill marks have been established.
