Small and sweet with just the mildest bit of heat, blistered shishito peppers are the perfect snack or appetizer.
In a large bowl, toss the peppers with the olive oil.
Add the peppers to a hot skillet and arrange in a single layer (cook in batches if necessary).
Cook, without stirring, until blistered underneath, 2 to 3 minutes.
Flip and cook until blistered in spots, puffed, and tender, another 2 to 3 minutes. Cover and cook for the final minute.
