Baked Asparagus with Balsamic Butter Sauce

Here's a yummy recipe that I found at allrecipes.com

Baked Asparagus with Balsamic Butter Sauce

1 bunch fresh asparagus, trimmed
cooking spray
salt and pepper to taste*
2 Tbsp. butter
1/2 Tbsp. soy sauce
1 tsp. balsamic vinegar

Preheat oven to 400 degrees. Arrange the asparagus on a baking sheet. Coat with cooking spray and season with salt and pepper. Bake the asparagus in the preheated oven for 12 minutes, or until tender. Melt the butter in a saucepan over medium heat. Remove from heat, and stir in soy sauce and balsamic vinegar. pour over the baked asparagus to serve.

(*I went easy on the salt since the sauce uses soy sauce. It's easy to season later if you feel it's necessary. I didn't need to.)
