Boil the prawns in salted water. I cook like this: for each liter of water, add 1.5-2 tablespoons of salt, 3-4 peas of coriander, 2 leaves of Lavrushka. Water poured from a calculation on 1 kg of shrimp to 2.5 liters. In a well prokopevsku the water, throw the shrimp, close the lid tightly until boiling and allowed to stand for 3 minutes. Remove the pan from the heat and leave them in the water for another 5 minutes. In my opinion, after this procedure, the meat becomes more juicy.
Shrimp drain in a sieve for a few seconds and dip in cold water - it will be easier to remove the meat from the shell.
Peeled shrimp cut lengthwise, if very small, it is possible not to cut at all)
Tomatoes, cut into quarters. Ordinary tomatoes just cut as you like.
Avocado remove the seed, remove the peel, cut it into cubes and immediately plenty of water with lemon juice. If you do not - the fruit will quickly turn black and lose its beautiful appearance.
Mix all the ingredients, add salt to taste and season with sauce - mix the oil and lemon juice in a ratio of 3:1.
