Shishitos are a unique pepper, coming from East Asia, so you can find them at almost any local grocery store in the United States. These unique peppers are a yellowish green to a bright green color. They taste a bit savory, mild, smoky, and sweet. You can eat them raw or cooked. If eaten raw, they taste similar to a bell pepper, but a little sweeter. The most common way to eat shishitos is blistered. Occasionally, you'll find a somewhat spicy pepper. Which is still much less spicy than your average jalapeño pepper.
