If using fresh corn, use a sharp knife to slice the kernels off the cobs into a medium bowl. If using frozen corn, ensure it is fully thawed and drained.

In a small jar or bowl, whisk together all the dressing ingredients: lime juice, olive oil, cumin, salt, and pepper until emulsified.

Gently combine the corn, halved cherry tomatoes, diced red onion, and chopped cilantro in a large serving bowl.

Pour the prepared lime dressing over the corn mixture. Toss gently until all ingredients are lightly coated.

Just before serving, carefully fold in the cubed avocado to maintain its shape and texture.

Taste and adjust seasoning if necessary. Serve immediately or chill for up to 30 minutes for flavors to meld.
