Halibut in Tomato Sauce with Beans

or two people:
halibut - between 3/4 and 1 lb., skin removed
6 scallions, chopped
2 cloves garlic, minced
3 T. olive oil
1 can cannellini beans (about 15 ounce can), drained and rinsed
1 can chopped tomatoes (about 15 ounce can)
1/4 cup dry white wine
salt, pepper to taste
fresh basil

Saute the scallions and onions in the olive oil until softened. Add the tomatoes and liquid from the can and cook for a few minutes, smashing the tomatoes a bit with a fork. Add the white wine, the cannellini beans, salt, pepper and shredded fresh basil. Simmer for about five minutes, then add the fish. Put a lid on the skillet, then let everything cook together for about five more minutes. That will be long enough to cook the fish. Garnish with more fresh basil and serve.
