Whole Wheat Lavash Bread Seasoned Roast Beef Cream Cheese Horseradish Red Onion-sliced thinly Tomato-sliced Green Leaf Lettuce This is an easy and amazingly delicious recipe. Mix 1 tsp horseradish into 1/4 cup cream cheese (or more if you can handle the heat!). Spread this mixture evenly over the lavash. Lay down one large leaf of lettuce down the middle of the bread, then a few slices of tomato. Sprinkle with slivers of red onion. Top this off with a generous mound of roast beef. Sprinkle with pepper. Roll like a burrito. Enjoy!
