Ingredients
1 flank steak (2 pounds)
1 Kosher salt and freshly ground black pepper
1 1/2 tbsp red wine vinegar
1 tbsp shallot, chopped
1/4 tsp Dijon mustard
1/4 cup extra virgin olive oil
2 bunches watercress, trimmed (8 cups)
1/2 cup crumbled stilton or other blue cheese
2 cups red California grapes, halved
Preparation
Preheat grill to high and oil grates. Sprinkle steak with salt and pepper.
In a small blender or food processor, combine vinegar, shallot, mustard and olive oil. Season with salt and pepper and purée until smooth. Grill steak until it reaches 130°F; for medium-rare this is about 6 to 7 minutes per side. Transfer to a cutting board and let rest 5 minutes.
In a large bowl, combine watercress, salt and pepper and enough dressing to coat.
Thinly slice steak across the grain and transfer to a platter. Top with watercress, stilton and grapes and serve with additional dressing.
