ISO: Fried flour tortillas with cinnamon and sugar

I am doing a cultural heritage project for my U.S. History class, in which we were assigned to make a cultural dish. I wanted to make a Mexican dish, and I have no idea what the name is of the easiest, cheapest dish that I've chosen.

You take flour tortillas, and cinnamon and sugar. You pour cooking oil in a pan, and fry the tortillas. Then, as soon and you take the tortillas out of the frying pan you sprinkle them with salt and sugar and let them dry (you can also eat them hot). My grandma said that she called them tostadas, but that she knows tostadas are somethin else. She also said that she thought they were called buenelos, but I think that's a dish involving meat...

Any help is greatly appreciated.
