Blanch the ear of corn in boiling water for 2 to 3 minutes then immediately transfer to an ice bath to stop the cooking. Once chilled, cut the kernels from the cob.
In a large bowl, combine the corn kernels, diced cucumbers, red onion, fresh dill, lemon juice, red wine vinegar, olive oil, grated garlic, salt, and pepper. Toss until well combined.
Cover and refrigerate for 20 to 30 minutes to let the flavors meld. If you need to serve immediately, make sure all the vegetables are well chilled beforehand.
When ready to serve, spread a thin layer of Greek yogurt over each naan round.
Spoon a generous amount of the corn and cucumber salad over the yogurt.
Top with crumbled feta and one Kalamata olive per bite. Serve immediately.
