Fish with Mushrooms in a Rich Tomato Sauce

I am proud to introduce this quick, easy dinner meal, using rich homemade or store-bought tomato sauce. Adding onions and garlic into this dish will bring out the sweet earthy flavor of the mushrooms.
Ingredients:
Two 6 oz firm white fish, cod, or tilapia
10 oz white button mushrooms
4 tbs coconut oil
1 sweet white onion, finely chopped
1 green chili, chopped
2 cloves garlic, minced
1 tsp ground cumin
1/2 tsp chili powder
1 tsp salt
1 tsp sugar
1/2 cup tomato sauce
2 tbs snipped fresh chives for tarnishing

Directions:
Cut fish into 1 inch pieces. Wipe the mushrooms with damp paper towels and thickly slice and set both aside
Heat the oil in a medium saucepan over medium heat. Add onion, chili and cook, stirring for 5-6 minutes until the onion is softened, but not brown. Add the garlic and cook, stirring  for 2 minutes.
Add cumin, chili powder and cook, stirring for 1 minute. Add mushrooms, salt, sugar and tomato sauce and bring to boil. Reduce heat to low, cover, and cook for 10 minutes, stirring halfway through. The sauce should have thickened, but if appears runny, cook uncovered for 3 minutes. Add fish and season with more salt, if needed. Simmer uncovered for 5 to 7 minutes or until fish is cooked through.
Transfer to a serving dish. Sprinkle with chives on top, and serve immediately.
