Mexican street corn skewers are a delicious twist on a classic street food. Grill corn on the cob until it is slightly charred. Cut the corn into smaller pieces and thread them onto skewers. Brush the corn with a mixture of mayonnaise, lime juice, chili powder, and crumbled cotija cheese. Sprinkle some chopped cilantro on top and serve the skewers with extra lime wedges for squeezing.
