Heat oil in a nonstick skillet over medium heat. Add peppers whole (do not remove stems or seeds), and toss to coat completely in hot oil. Sprinkle with 1/8 teaspoon salt.
Cook peppers, stirring frequently to be sure peppers are seared and blistered all over, for 9-10 minute. You will see the peppers change from a rich, bright green to a more yellow-ish green.
