I have made this a number of times, substituting a "cookie crust" made with the cookie of your choice (just use your smarts to match a good cookie that would compliment avocado). Garnish with a squeeze of lime juice, candied lime, lime zest, whipped cream or a combo of any or all. I use red limes and the fruitiness of the red lime is an amazing compliment. Also, make sure you use a very full flavored and high oil content avocado.
