Heat oven to 350. Place fish on a lightly greased pan. Sprinkle with taco seasoning and bake 10-20 minutes, until it flakes easily with a fork.
While fish cooks, heat oil in a large, heavy skillet over medium high. When it’s hot and begins to shimmer add onions and bell pepper. Cook, stirring frequently but allowing scotched patches to form, until crisp-tender. You’re aiming for something like fajitas.
Combine heated rice and black beans. Divide the mixture between two serving plates, spreading it into a circle.
Top rice and beans with bell pepper mixture.
When fish is done, place it on top of the bell peppers.
Top the fish with a line of pineapple salsa, a scoop of yogurt or sour cream, avocado and a drizzle of hot sauce.
