Carmen Rocha -- the woman credited with inventing nachos -- passed away this week at 77. A native of San Antonio, Rocha worked as a waitress at El Cholo restaurant on Western Ave. in Los Angeles since 1959. She's known for serving customers her special snack of tortilla wedges smothered with melted cheese and jalapeno slices and is remembered fondly by Jack Nicholson who said of Rocha's passing, "It's a community loss." At this year's Super Bowl, as we pass around the nacho platter, remember to lift a Margarita (a drink El Cholo also helped make famous) and toast Nacho Mama: Carmen Rocha. (Ted Scheffler)
