Slice and Bake Pumpkin

1 pumpkin (2-3 pounds), peeled and sliced into 1-inch thick pieces
1 tablespoon light cooking oil
2 tablespoons lemon juice
1 tablespoon soy sauce
2 tablespoons brown sugar
1 teaspoon ground cinnamon
1 teaspoon freshly grated ginger

Preheat oven to 325° F. Spread pumpkin pieces across a slightly oiled baking sheet. Combine remaining ingredients, and pour over pumpkin pieces (reserving a teaspoon or two). Toss to coat. Bake for 20 minutes, pour the remainder of the sauce over the pumpkin, and bake another 30 minutes or until done.
