Preheat oven to 375ºF. Peel and thinly slice potatoes. Arrange a layer of potato slices in the bottom of a buttered shallow baking dish. Sprinkle with a little lemon juice, salt, pepper and sugar. Top with some of the chopped green onion, crumbled bacon and grated cheese. Repeat until everything is used, ending with cheese. Pour the chicken broth and wine over the potatoes and bake for approximately 45 minutes or until potatoes are tender and top is browned. Garnish with green onion. Serves 4-6.
