Chipotle Black Bean Burger (vegan, gluten-free)

This is my working recipe for a vegan black bean burger. While I'm not a huge "spicy" person, I love chipotle peppers because they bring the heat without the burn. And canned chipotle peppers found at almost every grocery store come swimming in a delicious, sweet-smoky adobo sauce. In this recipe, both the peppers and the adobo sauce are utilized.
