Shrimp, Avocado, and Mango Salad

I just saw this on Desert Candy and I want to eat it.

--1 Mango
--1/4 of medium-sized Red Onion, finely diced
--2 tbsp finely diced Red Bell Pepper (or Hot Chili Pepper)
--A few Cilantro leaves, finely chopped
--3 tbsp Fresh Lime Juice
--1 Avocado, chopped
--1/2 lb Shrimp, peeled
--Salt and Cayenne Pepper to taste

Peel and slice the mango, working over a bowl. Squeeze the juice from round the pit of mango into the bowl. Add the onion, pepper, cilantro, lime juice and toss to combine.

Boil a pot of water with a little salt, then turn heat down to a simmer. Add the shrimp and cook until just opaque and curled in 3/4 circles. Don't overcook! Immediately transfer shrimp to a colander and run cool water over them to stop cooking. Dice the shrimp. Add the shrimp and avocado to the mango mixture. Season with salt and pepper to taste.
