Sweet potato black bean tacos are a super delicious plant-based taco choice! They are easy to make and full of protein. What's not to love? Tacos are often focused on rich meats, but we wanted a delicious version that was all about vegetables. Our favorite combination turned out to be sweet potatoes and poblano chiles, which we seasoned with fragrant garlic, cumin, coriander, and oregano. Roasting produced caramelized exteriors and tender interiors. Try these sweet potato black bean tacos for your next lunch or dinner!
