Grilled Denver Steak and Tomatoes with Caper-Mustard Vinaigrette

A bold and briny vinaigrette acts as both marinade and sauce for beefy grilled steak. Serve with garlic rubbed grilled bread and a green salad, if you like. If you can’t find Denver steak, substitute top sirloin or New York strip.

• 
  
  3 Tbs. red wine vinegar
  
  


• 
  
  2 medium cloves garlic, minced
  
  


• 
  
  1 Tbs. Dijon mustard
  
  


• 
  
  1/2 tsp. anchovy paste
  
  


• 
  
  1/2 cup extra-virgin olive oil
  
  


• 
  
  2 Denver steaks (about 8 oz. each)
  
  


• 
  
  Kosher salt and coarsely ground black pepper
  
  


• 
  
  1-1/2 lb. firm-ripe tomatoes (about 3 large), sliced 1/2 inch thick
  
  


• 
  
  2 Tbs. capers, rinsed and drained
  
  


• 
  
  1 Tbs. chopped fresh flat-leaf parsley
  
  

In a small bowl, combine the vinegar, garlic, mustard, and anchovy paste. Slowly whisk in the oil.

Put the steaks in a glass or ceramic dish large enough to hold them in a single layer. Reserve 1/4 cup of the vinaigrette and pour the rest evenly over the steaks. Cover and refrigerate for at least 2 and up to 24 hours. (Refrigerate the reserved marinade if not using within a few hours. Return to room temperature before using.) About 45 minutes before serving, remove the steaks from the refrigerator.

Prepare a medium-high (400°F) gas or charcoal grill fire. Take the steaks out of the marinade, letting any excess drip off, and season with salt and pepper. Grill for 4 minutes, flip, and grill until medium rare (130°F), about 4 minutes more. Transfer to a cutting board to rest for 5 minutes.

Meanwhile, season the tomato slices with salt and grill them on one side only until grill marks appear, about 3 minutes. Using a spatula, transfer them to a plate.

Whisk the capers and parsley into the reserved vinaigrette. Cut the steaks across the grain into 1/2-inch-thick slices and serve with the tomatoes and the vinaigrette.
