- Heat oil in large nonstick skillet over medium heat. Add onion, bell pepper, zucchini, eggplant, and garlic and cook, stirring occasionally, until vegetables are softened, about 10 minutes. Add tomato, tomato puree, tomato paste, 1/2 teaspoon of salt, and 1/8 teaspoon of pepper and cook, stirring occasionally, until vegetables are tender, about 5 minutes.
- Sprinkle fish with remaining 1/2 teaspoon of salt and remaining 1/8 teaspoon of pepper. Arrange fish in single layer on top of vegetables. Reduce heat to low and simmer, covered, until fish is just opaque in center, about 10 minutes. Sprinkle with basil just before serving.
- Per serving: 1 cod fillet and 1 1/2 cups vegetables
Strained tomatoes have been peeled, seeded, and pureed. Look for them in jars or cartons in larger supermarkets or specialty food stores. If you can't find them, use canned tomato puree.
