This easy white bean and spinach caprese salad features the classic combination of juicy tomatoes, creamy mozzarella, fragrant basil and tangy balsamic vinegar, but adds tender white beans and fresh baby spinach to the mix. If you can’t find mozzarella pearls, cut or tear a fresh ball of mozzarella into bite-size pieces instead. If you like your salad with a little kick, try swapping out the spinach for arugula.
