In a medium saucepan bring vegetable broth, chili powder, and cumin to boiling. Stir in oats. Reduce heat. Simmer, uncovered, 4 minutes, stirring occasionally. Stir in sweet potato and black beans; cook 1 to 2 minutes or until heated through. Remove from heat. Cover and let stand 2 minutes. Season to taste with salt.
Spoon oats into bowls. Top with avocado, salsa, cilantro, lime wedges, and, if desired, jalapeño pepper slices.
