Shishito peppers are specialty peppers from Japan. These 3"-4 " long peppers with wrinkled skin are used in tempura, yakitori or stir-fries. High in vitamins A and C, these peppers are hotter than bell peppers, but not as hot as chili peppers.
We love these peppers blistered in olive oil in a hot pan then lightly salted.
Look for these at your local farmer's market or a local Japanese market if you have one. Whole foods market stocks them sometimes.
There are some good substitutes if you can't find Shishito peppers:
