Ingredients

  • 2 teaspoons olive oil, plus more for grill

  • 2 large red onions, each sliced crosswise into 4 rounds

  • 1 tablespoon white balsamic vinegar

  • 5 tablespoons whole-grain Dijon mustard

  • Coarse salt and ground pepper

  • 2 pounds boneless pork loin, sliced into 8 equal pieces

Cook's Note

White balsamic vinegar is available in most supermarkets; white-wine vinegar is a good substitute.

Directions

  1. Step 1

    Heat grill to medium; lightly oil grates. Coat onion slices with 2 teaspoons oil. Place on grill. Cover; cook, turning once, until slices are charred in spots, 6 to 8 minutes. Transfer to a piece of foil; return foil with onions to grill. Cover, and continue cooking until tender, 10 to 12 minutes more.

  2. Step 2

    Transfer onions to a bowl. Toss with vinegar and 2 tablespoons mustard; season with salt and pepper. Cover to keep warm.

  3. Step 3

    Coat pork with 2 tablespoons mustard; season with salt and pepper. Place on grill. Cover; cook, turning when grill marks are visible, until meat is no longer pink in the middle, 6 to 10 minutes. Brush with remaining tablespoon mustard. Serve with grilled onions.

    This seems like such a simple, almost too simple recipe, but often simplicity is best- the mustard truly seals the chop juices, and the onions are a delicious compliment. Try it! My family loves this, and it could not be any easier!
