This hearty casserole combines the sweetness of roasted sweet potatoes with satisfying black beans, all baked in a flavorful enchilada sauce with melted cheese. It's a perfect vegetarian meal that's both comforting and easy to make.
For a spicier casserole, add a pinch of cayenne pepper to the sweet potatoes or a dash of hot sauce to the filling. You can also customize the cheese blend to your preference, using pepper jack for an extra kick.
