Orzo and Cheese Baked in Butternut Squash

• 2 small acorn squash, halved, seeded
• 3/4 cup water
• 1 cup orzo (rice-shaped pasta; also called riso) 
• 1 cup low-fat (1%) milk 
• 1/2 cup canned vegetable broth 
• 1/2 cup grated sharp cheddar cheese 
• 2 tablespoons freshly grated Parmesan cheese 
• Dash of hot pepper sauce (such as Tabasco)

Preheat oven to 400° F. Cut off thin slice from rounded side of each squash half. Arrange squash, open side down, in roasting pan. Add 3/4 cup water to pan. Cover tightly with foil. Bake until squash is tender about 35 minutes. Remove from oven; discard water. Turn squash open side up. Sprinkle with salt and pepper. Maintain oven temperature.

Meanwhile, cook orzo in pot of boiling salted water until almost tender, about 5 minutes. Drain. Pour milk and broth into same pot; bring to boil. Add orzo; boil until liquid thickens and orzo is tender, stirring frequently, about 5 minutes. Remove from heat. Stir in cheddar and 1 tablespoon Parmesan. Season with hot pepper sauce, salt and pepper. Divide orzo mixture among squash halves. Sprinkle with 1 tablespoon Parmesan. Bake until tops begin to brown, about 25 minutes.
