12 ounces shishito peppers
2 tablespoons vegetable oil
1/2 cup mayonnaise
2 tablespoons soy sauce
2 cloves garlic, grated
Kosher salt
Heat oven to 400F. Line a sheet pan with foil.
In a large bowl, toss together peppers and oil until peppers are coated. Season with salt and toss again. Spread into an even layer and roast until soft, about 7 minutes. Turn on broiler and broil until charred, about 2 minutes.
Meanwhile make mayo. In a small bowl, whisk together mayonnaise, soy sauce and garlic. Season with salt. Serve peppers hot with mayo on the side.
