Grilled Glazed Steak and Asparagus

1/2 C. oyster sauce
2 Tbsp. balsamic vinegar
1 tsp. grainy mustard
1/2 tsp. red pepper flakes
1 # medium asparagus, trimmed
1 1/2# flank steak

Prepare charcoal grill for direct-heat cooking over med-hot coals.

Stir together oyster sauce, vinegar, mustard, and red pepper flakes in a bowl.   Brush asparagus with some of the glaze.  Reserve.  Brush the steak with the remaining glaze and season with salt and pepper to taste.
Oil grill rack, then cook steak, turning once to medium rare, about 5 minutes per side.  Remove and let rest on a cutting board for 10-15 minutes.  Meanwhile put a wire vegetable rack down over the grill and cook the asparagus over the coals until tender, about 6-8 minutes.  If you don't have a wire rack, use metal or wooden skewers to hold asparagus, so they don't fall through the rack onto the coals.  Just thread asparagus crosswise onto 2 parallel skewers leaving space between each piece.
Put asparagus on a warm platter and cover.  Thinly slice the steak across the grain and arrange slices on the platter with the asparagus.  Serve and Enjoy!
