1. Prepare the Vegetables for Grilling

Start by preparing the vegetables for grilling. Wash and cut the zucchini into 1-inch slices, chop the bell peppers into chunks, and slice the red onion into wedges. If your mushrooms are large, cut them in half. The cherry tomatoes can be kept whole.

In a large bowl, combine all the prepared vegetables. Drizzle with olive oil, then sprinkle with dried oregano, garlic powder, salt, and pepper. Toss the vegetables to coat them evenly in the seasoning and oil. This step enhances the flavor of the vegetables and helps them cook evenly on the grill.

2. Prepare the Tzatziki Sauce

While the vegetables are being prepped, make the tzatziki sauce. Start by grating the cucumber. After grating, use a clean kitchen towel or cheesecloth to squeeze out as much moisture as possible. This is an important step to prevent the tzatziki from becoming too watery.

In a bowl, combine the grated cucumber with the Greek yogurt, minced garlic, fresh dill, lemon juice, olive oil, salt, and pepper. Mix everything well until smooth and fully combined. Taste the tzatziki and adjust the seasoning if needed, adding more lemon juice or salt for extra tang and flavor.

Refrigerate the tzatziki sauce for at least 10 minutes before serving. This helps the flavors meld together and ensures it’s cool and refreshing when served alongside the warm grilled vegetables.

3. Prepare the Skewers

If you’re using wooden skewers, soak them in water for about 10 minutes before grilling. This helps prevent the skewers from burning during the grilling process.

Next, thread the seasoned vegetables onto the skewers. You can alternate the vegetables as you go, placing them in an order that creates a visually appealing skewer. For example, you might start with a chunk of bell pepper, followed by a slice of zucchini, a mushroom, and a few cherry tomatoes. Repeat the pattern until the skewer is full.

4. Grill the Vegetables

Preheat your grill or grill pan to medium-high heat. If you’re using a grill pan, lightly grease it with some olive oil to prevent sticking. Once the grill is ready, place the vegetable skewers on the grill and cook for 10-15 minutes, turning occasionally to ensure the vegetables are evenly cooked and have nice grill marks.

The vegetables should be tender with a slight char, and the cherry tomatoes should burst open. Keep an eye on the grill to avoid overcooking the vegetables, as they can become mushy if left too long.

5. Serve the Grilled Vegetable Skewers

Once the vegetables are done, remove the skewers from the grill and let them rest for a few minutes. Serve the skewers with a generous side of the chilled tzatziki sauce for dipping.

You can serve the grilled vegetable skewers on a platter, garnished with extra fresh herbs or a sprinkle of feta cheese for added flavor. Enjoy the smoky, charred vegetables with the creamy, tangy tzatziki for a satisfying and healthy meal.
