In a large saucepan coated with cooking spray, saute shallots and garlic until tender. Add the tomatoes, broth, mixed vegetables, hash browns, seafood seasoning, sugar, allspice, cayenne and bay leaves. Bring to a boil. Reduce heat; simmer, uncovered, for 5 minutes or until vegetables are tender. Add halibut; simmer 2-3 minutes longer or until fish turns opaque. Just before serving, discard bay leaves. Yield: 4 cups.
