Trim and peel 2 large green plantains. Cut into 2in / 5cm slices.
Heat ⅔ cup of vegetable oil in a large skillet to 300°F / 150°C. Fry the slices for 3-5 minutes, turning once, until soft. Drain on paper towels.
Flatten each slice to about half its thickness. Heat the oil to 375°F / 190°C and fry until golden brown on both sides. Drain and sprinkle with ¼ teaspoon of salt.
