It might seem incongruous to include soy sauce in recipes that embrace the traditions of the wider Mediterranean, such as these shrimp skewers with Mediterasian Flavors. But the truth is that chefs, at least in Greece, have been incorporating this ancient condiment into Greek recipes for years now. Be judicious with your use of salt in this recipe, as soy sauce is high in sodium. Also look for organic soy sauce when possible.
In a medium bowl, combine soy sauce, balsamic vinegar, honey or petimezi, orange juice, lime juice, garlic, red pepper flakes. Add the shrimp and toss to coat. Cover and place in the refrigerator to marinate for 1-2 hours, tossing occasionally. If using wooden skewers, soak in warm water while the shrimp marinates. Meanwhile, prepare the pineapple if needed.
Lightly brush the grill with extra virgin olive oil, then place the skewers on the grill. Grill them for 3 minutes, brushing with the marinade, then turn and cook for an additional couple of minutes, brushing with the marinade again, until the shrimp are just cooked through. Remove to a serving plate and garnish with fresh herb of choice and scallions. Serve immediately.
