Chopped romaine salad with Piquillo peppers, hazelnuts and fried chickpeas

This vegetarian take on a chopped salad has all the creaminess of the original without the calories. A citrusy harissa-spiced Greek yogurt serves as the dressing for this big green salad, which is full of flavor and texture from roasted Piquillo peppers, Persian cucumbers, cherry tomatoes, hazelnuts and lightly fried smoky chickpeas.
