Prepare asparagus: wash and trim, toss in olive oil so they won’t stick to the grill.
Prepare Mustard Drizzle: whisk all ingredients together and set aside until asparagus are ready.
Grill: Carefully place oiled asparagus on the grill so they are perpendicular to the grill slats. Grill for 4 minutes and then gently roll to the other side so they don’t fall through. Grill another 4 minutes, or until desired tenderness.
Place grilled asparagus on a serving platter and drizzle with mustard sauce. Serve warm or at room temp.
Make a double batch because these will stay good in the fridge for up to a week and they are fantastic cold as left overs.
Notes
You may want to get an extra bunch of asparagus as they are tempting to eat straight from the grill.
