If you’re not familiar with the probiotic superfood kefir, it’s similar to yogurt, but thinner and tangier, and perfect for incorporating into all sorts of dishes, from breakfast smoothies to desserts. This chilled kefir, cucumber, and avocado soup is ultra refreshing on a hot summer day, and can be whipped up in mere minutes. Plus, it’s a cinch to scale up and makes a great light and healthy yet creamy and satisfying addition to a picnic or dinner party menu. Fresh mint and diced cucumber make bright garnishes; if transporting this, pack them separately and top off each bowl as you serve.

Note: The author uses Persian cucumbers, as she prefers to leave the skin on. If you can’t find Persian cucumbers, use any seedless variety.
