Vietnamese Steak Sandwich

Preheat grill to high.

Whisk fish sauce, lime juice, brown sugar and pepper in a shallow dish until the sugar dissolves. Set aside 2 tablespoons of the sauce in a small bowl for Step 4.

Place steak in a medium bowl, add oil and toss to coat. Oil the grill rack (see Tips). Grill the steak slices, turning once, until cooked through, 3 to 4 minutes total. Transfer to the dish with the marinade, stir to coat and refrigerate for 15 minutes or up to 8 hours.

To assemble sandwiches: Add mayonnaise to the reserved sauce and stir to combine. Spread the mixture on baguettes, top with the marinated steak, carrots, cucumber, daikon, scallions and cilantro. Slice the sandwiches in half.
