Place the tomatoes, garlic, salt and pepper in a saute pan set over medium heat; cook for 5 minutes, or until the tomatoes start to turn soft and start to blister.
Add the chicken stock, white wine (if using), frozen fish fillets and chopped basil. Cover and simmer for 20 to 25 minutes, until the fish is fully cooked.
Sprinkle with an additional handful of chopped basil and serve over a bed of rice, couscous or quinoa, if desired.
Notes
*Thick fillets of firm-fleshed white fish such as cod, hallibut, catfish or mahi-mahi work best for this recipe
