In a large bowl, tear the kale into bite-sized pieces. Drizzle with just a touch of olive and sprinkle very lightly with salt. Use your fingertips to rub the leaves, working in the oil and the salt. Keep massaging until the kale is soft and silky, and has turned a brighter green. Toss the avocado dices with lime juice and a big pinch of salt. Add the avocado, tomatoes, peppers, corn, green onions, and cilantro to the kale and toss well.
