Preheat your oven to 375 degrees F.
Arrange the cleaned and husked corn onto a baking sheet, roasting for 20 minutes; flipping them over halfway through the cooking period.
Once cooked, leave to cool before cutting off the roasted kernels with a sharp knife.
In a large bowl, combine the freshly roasted corn kernels, red onion, tomatoes, creamy avocado cubes, cilantro and jalapeño slices.
Whisk together lime juice, black pepper and salt in a separate bowl; pour over the vegetables and mix until thoroughly combined.
Serve up this mouthwatering roasted corn pico with avocado as is or pair it with tacos or use it to top a delicious salad.
