Drain the excess liquid from the salsa.

While the salsa is draining, make the avocado layer by mashing the avocados together with a little lime juice, salt and pepper.

Add the salsa to a large bowl (preferably a glass bowl for presentation - but not essential), then spread the avocado over the salsa.

Next, add a layer of sour cream and then shredded lettuce. You want to try and completely cover the avocado at this point, to help prevent it turning brown. Then cover with the shredded cheese.

And to finish, add some black olives and a sliced jalapeño.
