How to make Italian fish and vegetable stew
Season the fish with salt and pepper. \
In a medium bowl, whisk together the lemon juice, vinegar, mustard, and 30 ml of oil. \
Add the fish to the marinade, tossing to coat, and chill until ready to use. \
Cook the polenta according to the package instructions. \
Meanwhile, heat the remaining 15 ml of oil in a large frying pan over medium-high heat. \

Reduce the heat to medium-low. Add the tomatoes, garlic, fish, dressing, 1 tablespoon of slivered basil, and 1 teaspoon of chopped oregano. Season with salt and pepper. \
Cover and simmer until the fish is cooked through, about 5 minutes. Discard the garlic if desired. \
