Summer Vegetable Soup with Dill

Showcase summer's delicious bounty with a chilled buttermilk soup loaded with in-season vegetables and flavored with aromatic dill. This soup makes a great starter for just about anything you're putting on the grill for dinner tonight. If you have sweet, tender farm-fresh corn, use it raw. If your corn is a little starchy, blanch the ears in boiling water before cutting off the kernels.

  1 cup plain Greek yogurt, chilled

  3 Tbs. finely chopped fresh dill; more for garnish

  Kosher salt and freshly ground black pepper
  
  

Whisk the buttermilk and yogurt in a large bowl. Stir in the tomatoes, corn, fennel, cucumber, dill, 1 tsp. salt, and 1/4 tsp. pepper. Season to taste with more salt and pepper. Serve immediately or cover and refrigerate for up to 24 hours.

Serve the soup in chilled bowls, garnished with dill.
