½ teaspoon salt, divided
¼ teaspoon freshly ground pepper
1 tablespoon extra-virgin olive oil
1 shallot, chopped
2 cloves garlic, minced
¾ cup white wine

¼ cup heavy cream or half-and-half
½ teaspoon cornstarch
1Season fish with 1 teaspoon thyme, ¼ teaspoon salt and pepper. Heat oil in a large skillet over medium heat. Add shallot, garlic and 1 teaspoon thyme; cook, stirring, until beginning to soften, about 1 minute. Add wine, tomatoes and the fish to the pan; bring to a simmer. Cover and cook until the fish is cooked through, 4 to 6 minutes. Transfer the fish to a large plate; keep warm.
