To PrepCut the vegetables into bite sized chunks to be skewered. Finely grate the zest of the lime in to a bowl. After this, juice the lime in to the same bowl.Combine the lime juice, zest and the rest of the marinade ingredients in to a small bowl and whisk together until combined. Thread the vegetables on to either a metal or bamboo skewer and then place in to a large container. (If using bamboo or wooden skewers, allow them to be soaked in water prior to using them.)Once the vegetables have been skewered, pour over the marinade and let marinate for at least an hour. To CookRemove the vegetables from the container and shake off any excess marinade.Grill the vegetables, basting once every few minutes and turning over occasionally to ensure that the vegetables are cooked evenly.Continue to cook until they become soft and tender. Season the skewers to taste and serve!
