Equipment

Method
 

Make marinade and marinate
  1. Whisk olive oil, garlic, balsamic vinegar, Italian seasoning, and smoked paprika with salt and pepper until combined.
  2. Toss zucchini, red bell peppers, yellow bell peppers, red onion, cremini mushrooms, and cherry tomatoes in the marinade, then let sit 20 minutes.
Skewer and grill
  1. Thread the vegetables alternating colors and types onto skewers.
  2. Preheat the grill to medium-high, then oil the grates.
  3. Grill the kabobs 12–15 minutes, turning every 3–4 minutes, until the vegetables are charred and tender.
Serve
  1. Serve immediately with any remaining marinade drizzled over the kabobs.

Notes

Pro tip: For wooden skewers, soak them in water before threading so they don’t scorch on the grill. Refrigerate leftovers in an airtight container for up to 3 days; reheat on a hot grill or skillet until warmed through. Freezing isn’t recommended for best texture. For a lower-oil option, reduce olive oil to 2 tablespoons and add an extra 1 tablespoon of balsamic vinegar (still marinate 20 minutes).
