Grill the Corn. Remove the corn from the husks. Lightly brush it with olive oil. Grill over low-medium heat for 10-15 minutes, turning frequently. It should be tender to bite and slightly charred.
Prepare the Ingredients. Remove the corn kernels from the cob. Halve the cherry tomatoes and finely chop the red onion and cilantro.
Make the Dressing. In a small bowl, whisk together the olive oil, lime juice, honey, salt, and black pepper.
Combine the Salad. In a large bowl, combine the corn, tomatoes, red onion, and cilantro. Pour the dressing over the salad and toss gently to combine.
Serve. Garnish with crumbled feta cheese if desired. Serve immediately or refrigerate until ready to eat.
