Japanese Shishito and Spanish Padrón peppers are slightly spicy and are delicious blistered in extra virgin olive oil. Toss in cherry tomatoes if you have them and blister those as well.
Shishitos are usually mild, about 1 in 10 is medium-spicy. Padróns are also mild with a chance of about 2 in 10 being medium-spicy.
They make a wonderful appetizer or side dish.
