Make the dressing
Add the oil, lime juice, red wine vinegar, honey, Dijon mustard, salt, parsley, black pepper, cumin, garlic powder, and chili powder to a jar with a lid.
Shake until the dressing looks smooth and well combined. Refrigerate it while you prepare the salad.
Cook the corn
Bring a large pot of water to a boil. Add salt to the water, then add the corn.
Boil the corn for about 4 minutes, just until tender and bright.
Cool the corn
Transfer the corn to a colander and rinse with cold water until completely cooled.
Pat the corn dry before cutting.
Cut off the kernels
Place each cob upright or flat-side down on a cutting board.
Use a sharp knife to slice the kernels from the cob. Add the kernels to a large mixing bowl.
Add the vegetables
Add the bell peppers, cherry tomatoes, cucumber, red onion, and cilantro to the bowl with the corn.
Gently toss to combine.
Add cheese and dressing
Sprinkle in the Cotija cheese.
Shake the dressing again, pour it over the salad, and toss until everything is lightly coated.
Serve or chill
Serve right away for the freshest crunch, or cover and refrigerate for up to 1 day before serving.
