Add plantain pieces to the boiling water and cook until very tender, about 50 minutes. The peel should slip off the plantain and you should be able to pierce the pieces easily with a fork.
Drain and let cool about 15 minutes.
Remove the peel and place the pieces in a food processor. Process until smooth and dough like. (You may have some small chunks and that is fine.)
Form dough into 6 or 8 balls. Flatten using a tortilla press, your hands, or a heavy flat bottomed skillet.
Cook in a nonstick skillet, one at a time, flipping occasionally. Or you can cook on an electric griddle heated to 350 degrees, flipping occasionally. The dough will puff up a little and will brown slightly on both sides.
Cut up and dip into salsa or top with your favorite grilled veggies.
