Lupe's Ensalada de FrijolesLupe Fregoso, a friend all through my school days, invited me to have lunch in her home when we were about nine years old. It may have been my first taste of Mexican food. Although I have long forgotten what else we had, I vividly remember the bean salad, and soft, warm, corn tortillas that we ate with the salad as you would a piece of bread. The Fregoso family was from the state of Jalisco, near Guadalajara, and the salad probably reflected what native ingredients were available to her family in our northern California home. Although authentic Mexican ingredients are now more readily available, this simple salad, based on memory, is good even today, especially with the warm tortillas.
