Line a large baking sheet with foil for easy cleanup. Preheat oven to 230°C (450°F).
02 -
Brush both sides of the tortillas with oil and place on the prepared baking sheet (they'll be very close together but will shrink slightly during baking). Bake for 9 to 10 minutes, until firmed up but not overly browned or crisp.
03 -
Remove the baking sheet and let the tortillas rest for about 5 minutes or until cool enough to handle.
04 -
Flip the tortillas over and spread each one with refried beans. Top with chicken and cheese.
05 -
Return the tostadas to the oven and bake for an additional 5 to 6 minutes or until the beans and chicken are heated through and the cheese is melted.
06 -
Top each mini tostada with a small dollop (about 1 teaspoon) of sour cream, diced onion, tomato pieces, and cilantro. Serve with hot sauce.
