Mexican street corn salad is a flavorful and refreshing side dish for a Mexican food dinner. Grill or roast corn on the cob until it is charred, then cut the kernels off the cob. Toss the corn with mayonnaise, lime juice, chili powder, and crumbled cotija cheese. Add diced red onion, jalapeno, and cilantro for extra flavor and crunch. Serve the salad chilled as a side dish or as a topping for tacos.
