Roast Beef Wrap

Ingredients:

2/3 cup sour cream
2 TBS drained bottled horseradish, or to taste
4 flour tortillas or lavash
1 bunch watercress
1 lb thinly sliced roast beef
1 firm tart apple or Asian pear, cored and sliced into very thin wedges
4 TBS crumbled blue cheese

Stir together sour cream and horseradish in a small bowl. To assemble, spread a tortilla evenly with 1 heaping tablespoon of the horseradish mixture. Cover with watercress and a quarter of the roast beef, making sure the ingredients don't quite touch the edges. Spread another heaping tablespoon of the horseradish mixture over the top, followed by a quarter of the apple or pear slices, and 1 tablespoon of blue cheese. Roll up the tortilla. Complete the wraps with the remaining ingredients. Cut in half on the bias. 4 servings.
