Instructions

  1. Preheat oven to 400 degrees. Arrange asparagus spears in a 9x13-inch baking dish (or similar). Coat the top of asparagus with cooking spray, then season with salt and pepper to taste.
  2. Bake asparagus until tender (about 10 minutes depending on thickness of spears).
  3. Melt butter in a small, nonstick saucepan over medium heat, then remove pan from heat. Stir in the soy sauce and vinegar to make a sauce. Pour the sauce over the baked asparagus spears and serve.
