Place the butter, graham crackers, and almonds into a food processor.
Cover, and pulse until the mixture resembles a coarse crumb.
Transfer the crumbs to a 9-inch pie plate, and press into the bottom of the plate to form a crust.
Wash and dry the bowl of the food processor; set aside.
Bake in the preheated oven until lightly golden, about 15 minutes.
Remove from oven, and cool for 15 minutes.
Meanwhile, melt the chocolate in the top of a double boiler over just-barely simmering water, stirring frequently and scraping down the sides with a rubber spatula to avoid scorching.
Place the chocolate, tofu, and vanilla extract into the cleaned food processor.
Blend until smooth, scraping down the sides several times.
