Ingredients
  

Bread

  • 1 loaf French Bread sliced diagonally into about 1/2 inch to 1 inch pieces
  • 2 tbsp extra virgin olive oil
  • 1/2 cup lightly chopped arugula
  • 3/4 lb sliced roast beef
  • 8 oz cream cheese, softened
  • 3 tbsp chopped fresh chives
  • 2 tbsp minced fresh oregano
  • 1/2 tsp coarse sea salt
  • 1/4 tsp fresh cracked black pepper
  • 1/4 cup sour cream
  • 3 tbsp Dijon mustard
  • 1/8 cup mayonnaise
  • 1/8 cup stone ground mustard
  • 1-2 tbsp prepared horseradish to taste; start with 1 tbsp
  • 1 tbsp extra virgin olive oil

Onions

  • 2 large yellow onions
  • 4 tbsp butter

Instructions
 

  • Mix cream cheese, chives, oregano, salt, and pepper for the spread; set aside. Prepare horseradish cream and set aside.
  • Slice bread, brush with olive oil, and broil for 3-5 minutes until lightly toasted. Remove and set aside.
  • Caramelize onions: sauté sliced onions in olive oil over medium heat for 5 minutes, then add butter and cook on low until golden and limp (~20 minutes).
