In a small sauce pan, place the shrimp and cover by half an inch with water. Bring the water to simmer and cook for 3-4 minutes, until the shrimp are pink and curled. Drain and rinse under cold water, then peel the shrimp. Chop roughly, place in a small bowl, cover and refrigerate. In a bowl, combine remaining ingredients and toss well. Adjust seasoning with lime juice and salt, to taste. Cover and chill one to two hours to allow flavors to melt. Add shrimp to salsa and toss to combine. Taste, and adjust seasoning as needed. Cut each Fresh California Avocado in half length wise. Remove the pit. Score each half, leaving the Fresh California Avocado in the shell. Divide the salsa among the six avocado halves, filling the cavity and mounting it up on top. Squeeze a little bit of lime juice over all and garnish with some cilantro leaves.
