01 - Preheat a grill or grill pan to medium-high heat. Place the husked corn on the grill and cook for 8 to 10 minutes, turning occasionally, until kernels are well-marked with char spots and tender throughout. Remove from heat and let cool slightly.
02 - Stand each cooled ear of corn upright on a cutting board. Using a sharp knife, slice the kernels off the cobs in long downward strokes. Transfer the kernels to a large mixing bowl and discard the cobs.
03 - Add the diced avocado, pineapple, mango, red bell pepper, red onion, and chopped cilantro to the bowl with the charred corn kernels.
04 - In a small bowl, whisk together the extra virgin olive oil, fresh lime juice, honey or agave syrup, ground cumin, sea salt, and black pepper until the mixture is fully emulsified and no oil separation remains.
05 - Pour the prepared dressing over the salad ingredients. Gently toss everything together using a large spoon or spatula, taking care not to mash the avocado, until all components are evenly coated.
06 - Sprinkle with the finely diced jalapeño and toasted pumpkin seeds if desired. Serve immediately at room temperature or chill briefly before serving. A pinch of chili powder on top adds an extra layer of flavor.
