Grilled Vegetable Salad with Smoked Paprika Vinaigrette

• 3/4 pound small new potatoes, quartered
• One 16-ounce can chickpeas, rinsed and drained
• 2 cloves garlic, coarsely chopped
• 2 tablespoons plus 2 teaspoons red wine vinegar
• 1 1/2 teaspoons sweet smoked paprika
• 1/2 cup extra-virgin olive oil
• Salt
• 4 portobello mushroom caps (1 pound)
• 3 zucchini (1 pound total), sliced lengthwise 1/2-inch thick
• Pepper
• 1/2 bunch fresh basil, leaves shredded and stems discarded

1. In a large pot of boiling, salted water, cook the potatoes until fork-tender, about 7 minutes. Drain and transfer to a large serving bowl. Add 1 1/2 cups chickpeas.
2. Using a blender, puree the remaining chickpeas, garlic, vinegar and paprika with 2 tablespoons water. Pour in the olive oil in a slow, steady stream, processing until combined; season to taste with salt. Pour 1/4 cup dressing over the potato mixture and toss.
3. Preheat a grill or grill pan to high. Brush some remaining dressing on the mushrooms and zucchini, then season with salt and pepper. Grill the zucchini for 1 minute per side and transfer to a cutting board. Grill the mushrooms gill side up for 2 minutes; rotate 90 degrees and grill for 2 minutes more, then flip and grill until slightly charred, about 1 minute more.
4. Chop the zucchini and mushrooms into 1/2-inch cubes and add to the potato mixture. Add the basil and season with salt and pepper; toss to combine. Serve with remaining dressing on the side.
