You will need 2 bowls for the assembly. In the first bowl combine the avocados, juice of 2 limes, salt and pepper. Mix this together until it is of chunky consistency. In the other bowl combine the crab meat, basil, salt, pepper and the juice of the last lime. Carefully mix together, being careful not to pull apart the meat.

Arrange your tortilla chips on a serving platter and place a spoonful of the avocado mixture on the bottom and then a spoonful of the crab on top. If you have any extra basil you can add it to the top of the chip.
