Mediterranean Grilled Vegetable Skewers are a fun and easy way to get in some extra veggies. This mediterranean veggie kabob marinade means your shish kabob skewers will be so tasty, everyone will love them. If you presoak your skewers, you can have this prepped, marinated and grilled in under 30 minutes.
Place wooden skewers on a flat tray with sides and cover with water. Soak skewers for a minimum of 30 minutes to prevent them from catching fire on the grill.
Prepare Veggies: slice zucchini and squash in half lengthwise and then into 1" pieces. Cut onion into quarters and then eighths, scrub mushrooms with a damp paper towel and snap off stems. Stem, seed and core peppers and then slice into pieces that are similar in size to the other veggies.
Prepare Marinade: Zest lemon and squeeze juice over medium sized bowl. Zest garlic with same microplane. Whisk in remaining ingredients and mix until everything is well incorporated. Set marinade aside.
Place all veggies except mushrooms (the mushrooms will act like sponges and soak up all of the liquid--so give the other veggies a chance!!) into bowl with marinade and mix well. Toss in mushrooms and continue to stir until all vegetables are coated. Cover and let sit for at least 30 minutes, or up to 6 hours.
Thread veggies onto pre-soaked skewers, reserving any leftover marinade.
Preheat grill to medium heat.
Place skewers on heated grill and close lid. After 3-4 minutes, when grill marks begin to show, turn skewers with tongs. Continue until all sides have been "marked" and veggies are tender. Brush with additional marinade half way through if the veggies seem dry.
Cooked skewers can be stored in fridge (it is easier to store the veggies if you take them off the skewers) for up to a week in a tightly sealed glass container.
Notes
PRO TIP: Make sure to clean your grill really well before beginning. Those little bits stuck on there from cooking proteins contain carcinogens. Heat your grill to high. Let those bits turn ashy-gray and then use a metal grill brush to scrape them off.
