Update;
Took them to a decent Taqueria for lunch and took me 1/2 an hour to explain the menu. One guy ordered a Chili Relleno with shrimp and the other Chili Colorado. Both were pleasantly surprised and cleaned their plates. I did have to explain "Frijoles Refritos" though and they were worried about what to expect. Like I said, both plates were cleaned. I so enjoy watching people enjoy a good meal.
