Avocados were once securely on the list of foods to avoid just because of their fat content, but new research has shown that the green cream of the avocado is chock full of good fat. Which is good news for everybody who loves his or her guacamole (for those who don’t know, guacamole — pronounced gwah-kah-MOH-lee—is a traditional Mexican dip and garnish featuring avocados and salsa, and sometimes sour cream). On the grill, avocado takes on a delicious smoky flavor, making it a savory appetizer.
