The only reason you think cucumber sandwiches are boring is because you haven't had one that is made right, says chef Vishwesh Bhatt. Benedictine, a creamy spread of cucumber and herbs; along with a spicy and herbaceous peanut pesto with serrano chile, cilantro, and citrus; and chaat masala add verve to these sandwiches. And after layering in the crisp cucumbers, spicy chile slices, and juicy tomatoes, take a bite. "Once you serve this one, it's going to become a fixture at your summer parties," Bhatt says.
