It's almost Cinco de Mayo, the perfect day to enjoy some freshly made guacamole. However, you don't need to serve this only on the 5th of May; it's delicious anytime! And, as far as snacks go, it's pretty healthy too! In fact, did you know that a typical serving of avocado (1/3 of one) has only about 80 calories, 7g of healthy fat, 3g fiber and lots of essential vitamins.
