If using fresh corn, roast it on a grill or in the air fryer until lightly charred. Let cool and cut from the cob. If using frozen corn, roast in a hot cast-iron skillet until charred spots appear.
Wash your peppers thoroughly and pat them dry. Cut them in half lengthwise and remove the seeds and membranes. (This is the easiest way to ensure even cooking). Roast the red bell peppers in the air fryer, under the broiler, or on an open flame until skin is blackened. Transfer them to a large bowl and cover with plastic wrap or place them in an airtight container to steam, then peel, and dice.
In a large bowl, combine the drained and rinsed black-eyed peas, roasted corn, diced roasted bell peppers, red onion, green onions, cherry tomatoes, jalapeño pepper, minced garlic, and chopped cilantro.
Whisk together the ⅓ cup olive oil, ¼ cup fresh lime juice, 2 tablespoons honey, 1 teaspoon ground cumin, 1 teaspoon black pepper, and salt in a separate bowl until well combined and honey is fully incorporated.
Pour the dressing over the vegetable mixture and gently toss to coat evenly.
Cover with plastic wrap or transfer to an airtight container and refrigerate for at least 2 hours or overnight for best results.
Just before serving, gently fold in diced avocados and extra fresh cilantro if desired.
