Want to celebrate St. Patrick's Day with something green, but you're not too keen on food coloring in milk, or bright green beer? Here's something to put you in the mood, made with an unexpected and extremely un-Irish ingredient: Avocados! This pie is from Jessica Jones at How About Orange. She found the recipe at the California Avocado Commission, and she whipped up this super simple pie. It only has four ingredients (not including the graham cracker crust).
