In a small mixing bowl, whisk together lime juice, honey, cayenne pepper, garlic powder, onion powder, salt, and pepper. Gradually drizzle in olive oil while whisking to emulsify.

Bring a large pot of water to a boil, add sugar and lime juice, then add corn. Cover and let sit for 10 minutes before plunging into ice water.

Once cooled, slice the kernels off the corn and place in a bowl.

Combine corn, diced red bell pepper, halved grape tomatoes, chopped cilantro, finely sliced scallions, minced jalapeno, crumbled feta, and sliced red onion in a large salad bowl. Toss gently.

Drizzle the vinaigrette over the salad, toss gently until combined, taste and adjust seasoning if necessary.
