Preheat oven to 350 degrees.
Line up the asparagus in a covered casserole that will hold all of them in no
more than 2 layers. Season lightly with salt and pepper. Add water and cover.
Place in preheated oven for 15-17 minutes. Meanwhile, melt butter in a small
saucepan. When it's hot, but not yet brown, add pecans. Stir a few seconds until
they just turn color. Add vinegar, stirring once more and spoon over cooked
asparagus. Serve immediately. Yield: 6 servings.
