1 C. dry sherry
3 cloves garlic, chopped
2 shallots, chopped
1/4 C. sherry vinegar
1 tsp. green peppercorns
1/3 C. extra virgin olive oil
1 T. chopped fresh thyme
Salt
Freshly ground black pepper

 

Soak 12 bamboo skewers in a pan filled with water for at least 30 minutes, then dry them with a kitchen towel. Put the vegetables on the skewers and set aside. To prepare the marinade, combine the sherry, garlic, and shallots in a small sauté pan over high heat and reduce until about 1 T. of the sherry remains. Transfer the sherry mixture to a medium bowl and add the sherry vinegar and peppercorns. Whisk in the olive oil until emulsified. Add the thyme and season to taste with salt and pepper. Pour the marinade over the vegetables and set aside to marinate for at least 30 minutes.  In the meantime, prepare the grill. Place the skewers on the hot grill and cook, occasionally brushing the vegetables with the leftover marinade. Cook for 5 to 8 minutes, or until the vegetables are crisp-tender. Remove skewers from the grill, set on a platter, drizzle with remaining marinade, and serve immediately.
