Preheat an outdoor grill to medium-high.
Brush corn with oil and season with salt, then grill for 6 to 8 minutes, until it is tender and charred in spots.
Allow corn to cool slightly, then cut into smaller bite-sized pieces if desired (this is great for picnics or parties where you aren’t really sitting down to eat!).
Transfer corn to a serving platter and drizzle with extra-virgin olive oil and lemon juice. Scatter mint and red pepper flakes over top. Serve immediately or at room temperature!
