Here's a fun Korean spin on a classic Mediterranean appetizer. A drizzle of toasted sesame oil enhances the nuttiness of tahini (sesame seed paste) in this quick make-ahead dip, and rice vinegar stands in for the usual lemon juice. Kimchi gets blended into the hummus, where it adds a hint of savory pickled essence. It's also chopped and sprinkled on top for a burst of fermented pungency. Serve with sliced cucumbers, whole radishes, raw cauliflower florets, baby carrots, and rice crackers.
