Toss with about a tablespoon of olive oil (enough to coat lightly).
Place peppers on the grill. Leaving the grill lid open, cook for 7 to 10 minutes, turning occasionally. They are done when soft and blistered.
Put peppers back in the original bowl and toss to cover in remaining oil.
Transfer to a platter and sprinkle with flaky sea salt.
Serve warm or at room temperature.
Notes
* Can be made a few hours in advance. Cover and store at room temperature. * Recipe can be doubled or tripled. * Peppers can also be cooked on top of the stove in a hot frying pan.
