Authentic Mexican Tostadas
Both the roast and beans can be prepared a day or so beforehand.
If you are frying your own tostadas, use a frying pan with plenty of oil over high heat. Once the frying pan is hot, place a corn tortilla into the pan, pressing down with a large cooking utensil, not allowing the tortilla to get bubbly. Cook until nice and crispy, about 2 minutes on each side.
