Heat a nonstick frying pan over a medium-low heat and dry-fry the sesame seeds for 2 minutes, stirring frequently, until golden brown and toasted.
Set aside.
Meanwhile, place the avocados in a large bowl and toss with the lime juice to prevent discoloration.
Gently toss together with the remaining ingredients except the sesame seeds.
Sprinkle the salad with the toasted sesame seeds and serve.
