Preheat your oven to 375 degrees.

Place chicken breasts in a baking dish. Brush both sides with olive oil and season generously with salt and pepper.

Cover dish with aluminum foil. Bake for 1 hour or until the juice from the chicken run clear and chicken reaches an internal temperature of 165 degrees. Use an instant read thermometer placed in the thickest part of the breast. Let chicken cool for a few minutes. Then, shred the meat and discard the bones.

Heat refried beans according to the instructions on the can.

Arrange the toppings in small bowls or plates. I give a bunch of toppings in the ingredient list, but feel free to add anything else that you enjoy.

Let your family (or guests) build their own tostadas. I usually like to put the refried beans on first because they hold the tostada together nicely.
