In medium bowl, mix cream cheese, Gouda cheese and bacon bits until well blended. Stir in tomatoes. Cover; refrigerate 45 to 60 minutes or until firm enough to shape into balls.
Place pecans or parsley in small shallow bowl. Shape cheese mixture into 28 (1-inch) balls, about 2 teaspoons cheese mixture for each ball. Roll in pecans to coat.
