Asparagus Spears with Garlic Mustard

1/2 pound asparagus spears, trimmed
1/8 cup butter or margarine
1 cs. fresh mushrooms, sliced
1 tablespoon country-style Dijon mustard
1/8 teaspoon pepper
Pinch of salt
1/4 teaspoon minced fresh garlic

In 10 inch skillet place asparagus spears; add enough water to cover. Bring to a full boil. Cook over medium heat until asparagus is crisply tender (5 to 7 minutes). Drain; return to skillet.

Add remaining ingredients, pushing asparagus to side just until butter is melted. Cook over medium heat, stirring occasionally, until heated through (5 to 7 minutes).
