01 - In a small bowl, mix vegan mayonnaise, minced chipotle peppers, adobo sauce, lime juice, and salt. Cover and refrigerate until ready to use.
02 - In a large bowl, mash the black beans with a fork or potato masher, leaving some texture for hearty consistency.
03 - Add the red onion, garlic, oats, breadcrumbs, cilantro, tomato paste, cumin, smoked paprika, chili powder, salt, and black pepper. Mix thoroughly until combined.
04 - Divide the mixture into 4 equal portions and shape into burger patties. If the mixture is too wet, add extra breadcrumbs as needed.
05 - Heat olive oil in a large skillet over medium heat. Cook the patties for 4–5 minutes per side, until golden brown and heated through.
06 - Toast the burger buns if desired for added texture.
07 - Spread chipotle mayo on each bun, add a black bean patty, then top with lettuce, tomato, onion, and avocado as desired.
08 - Serve immediately with sweet potato fries or a crisp salad.
