Add some heat to your veggie sandwich with this spicy black bean and corn creation. Start by mashing black beans with a fork and mixing them with corn kernels, diced red bell pepper, jalapeno, and a squeeze of lime juice. Season with cumin, chili powder, salt, and pepper. Spread the black bean and corn mixture on whole grain bread and top with sliced avocado and fresh cilantro. This sandwich is not only packed with flavor but also provides a good source of plant-based protein and fiber from the black beans.
