This green sauce is popular in many Mexican restaurants around Houston. Ninfa's was one of the first to serve this sauce. The recipe has been printed in the Houston Chronicle several times. I've adapted it slightly. Mama Ninfa Rodriquez Laurenzo opened the original Ninfa's Restaurant on Navigation street in 1973. Her food differed from the usual Tex-Mex restaurants in town. She seemed to achieve fame in the kitchen overnight. Some of her famous guests included George Bush, Michael Douglas, John Travolta, Rock Hudson, and Aerosmith! Mama Ninfa lost her battle with cancer last year, but her much loved Mexican food lives on. The original Ninfa's is still there, and there are several other locations here in Houston as well.
