L'Entrecôte Salad Dressing

 So simple, so good - from a steakhouse restaurant in Bordeaux France. 

• 1 tablespoon Dijon mustard
• 1 tablespoon white wine vinegar
• Kosher salt
• Freshly cracked black pepper
• Extra-virgin olive oil
• Toasted walnuts for topping

Topping with toasted walnuts makes the salad!
