1. Preheat your grill to medium-high heat and let it get screaming hot for at least 10 minutes. Clean the grates well and oil them lightly to prevent sticking.
2. While the grill heats, slice your zucchini and yellow squash into 1/2-inch thick rounds—not too thin or they’ll turn mushy. Cut the bell pepper into wide strips, slice the red onion into thick rounds keeping rings together, and leave cherry tomatoes whole.
3. In a large bowl, combine all your vegetables with olive oil, minced garlic, oregano, salt, and pepper. Toss everything really well with your hands, making sure every piece is coated—this prevents sticking and builds flavor.
4. Transfer the seasoned vegetables to a grill basket in an even layer without overcrowding, or thread onto metal skewers alternating types. If using skewers, soak wooden ones in water for 30 minutes first to prevent burning.
5. Place your grill basket or skewers on the hot grill. Here’s the key: let them sit for 3-4 minutes without moving so they develop those gorgeous char marks we’re after.
6. Turn the vegetables with tongs, cooking another 3-4 minutes per side, about 2-3 turns total. They’re done when tender with beautiful grill marks—about 10-15 minutes total depending on your grill’s heat.
7. Transfer these beauties to a serving platter while still hot. Serve immediately as a side dish, or over cooked quinoa or rice for a complete vegetarian meal that’s incredibly satisfying.

Notes:

• Seriously, let your grill get hot before adding vegetables—this is crucial for proper char marks

Storage Tips:

Keep leftover grilled vegetables in an airtight container in the fridge for up to 4 days. They’re delicious cold or at room temperature, making them perfect for meal prep. Reheat gently in a 350°F oven for 10 minutes or enjoy them cold in salads, wraps, or grain bowls. Don’t freeze these—the texture gets mushy when thawed. These actually taste great the next day, so don’t hesitate to make extra.
