Ingredients

Instructions

  1. Step 1: In a medium bowl, whisk together 3 tbsp olive oil, 2 tbsp harissa paste, 1 tbsp lemon juice, 1 tsp ground cumin, 1 tsp smoked paprika, 1 tsp salt, and 1/2 tsp black pepper until well combined.
  2. Step 2: Add 1 large red bell pepper cut into 1-inch pieces, 2 medium zucchini sliced into 1/2-inch rounds, 1 large red onion cut into wedges, and 12 whole button mushrooms to the marinade. Toss gently to coat all vegetables evenly. Cover and refrigerate for 30 minutes to absorb flavors.
  3. Step 3: Preheat a charcoal grill to medium-high heat, letting the coals develop a thin layer of white ash (about 10-15 minutes).
  4. Step 4: Thread the marinated vegetables onto skewers, alternating pieces for color and texture. Place the skewers on the grill and cook for 10-12 minutes, turning every 3 minutes, until vegetables are tender and have charred grill marks.
  5. Step 5: Remove from grill and sprinkle with 2 tbsp chopped fresh cilantro before serving warm.
