Grill the corn. Put your husked ears of corn right on a hot grill. Cook them for about 10 minutes. Turn them every few minutes so they get a nice char on all sides.
Cool and cut. Let the corn cool down so you do not burn your fingers. Then, carefully slice the sweet kernels off the cob into a large bowl.
Mix it up. Toss the diced avocados, cherry tomatoes, red onion, and fresh cilantro into the bowl with your corn.
Make the dressing. In a small bowl, whisk the fresh lime juice and olive oil together.
Toss gently. Pour the dressing over the salad. Add a pinch of salt and pepper. Stir it very gently so you do not mash up those beautiful avocados.
Serve and enjoy. You can eat this right away or let it chill in the fridge for a bit.
