Heat oven to 375° F. Mix cut plantains in a bowl with olive oil and a pinch of salt.
Place plantain pieces on a cookie tray and bake in oven for 10 to 15 minutes.
Remove plantains, flip them over and smash to create a thick cookie-like texture. Return pan to oven for 10 more minutes or until dark brown and crisp. Add salt to taste, if desired.
Enjoy topped with refried black beans and cheese, or with your favorite salsa.
