01 - Preheat a grill or grill pan to medium-high heat. Place the husked corn directly on the grill and cook for 8–10 minutes, turning every couple of minutes, until the kernels are well-marked with char spots and tender throughout. Remove from the grill and let cool slightly.
02 - Stand each cooled corn cob upright on a cutting board and carefully slice the kernels off in strips. Transfer the kernels to a large mixing bowl.
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, lime juice, honey or agave syrup, ground cumin, sea salt, and black pepper until the mixture is well emulsified and smooth.
05 - Pour the dressing over the salad mixture and gently toss everything together using a large spoon or spatula, being careful not to mash the avocado.
06 - Top with finely diced jalapeño and toasted pumpkin seeds if desired. Serve immediately at room temperature or chilled.
