Shishito peppers are a mild Asian variety of pepper. When sautéed, they make for a delicious, healthy appetizer. As a result, they’re quickly gaining popularity with vegetable gardeners and foodies alike. Shishito peppers are small and green, with a thin skin. They appear similar to the Spanish Padrón pepper (which is served the same way) but are less spicy and more wrinkled. Though shishito peppers are usually very mild, one in every ten is spicy. The larger shishito peppers grow, the more potential they have for heat.
