My trick to Cinco de Mayo is to go easy on the chips in the beginning and to wait for the good stuff. The warm homemade tortillas for my beef and shrimp fajitas are the real treat. Enter guacamole. In my opinion, guacamole can single handedly take a salad or fajita from a 2 star to a 5 star status. Besides being delicious, avocados have a abundance of monounsaturated fats that improve heart health.
