Clean and remove tough ends from asparagus. Spray cookie sheet with Pam. Lay asparagus out side by side. Salt and pepper asparagus and roast at 400 degrees for 10-12 minutes. While cooking, brown 2 T butter, remove from heat and add 1 tsp. balsamic vinegar and 2 tsp. soy sauce. When asparagus is done, drizzle butter mixture over asparagus. It is SOOOO yummy!
