1/2 pound fresh padron, shishito, seranno, small Hatch, or hot banana peppers, washed and thoroughly dried
1 tablespoon olive oil
Coarse sea salt, such as fleur de sel or Maldon

Place the peppers in a medium bowl, add the olive oil, and toss to coat; set aside.

Heat an indoor sautee pan or outdoor grill to medium high.

When the grill is ready, place the peppers on the grill in a single layer, making sure they’re not touching; reserve the bowl they were in. Grill the peppers uncovered, turning them occasionally, until they start to char and blister, about 6 to 8 minutes total.

Return the peppers to the bowl, toss immediately with the salt, and serve.
