4 servings


1 1/2 pound London broil
1/2 cup olive oil, plus more for brushing steak
Salt and pepper
1/4 cup balsamic vinegar
4 portobello mushroom caps, cut in slices
1 Vidalia onion, cut in rings
1/2 cup mayonnaise
1 tablespoon grated horseradish or grainy mustard
1/2 cup chopped fresh parsley
1/2 lemon, juiced
4 pieces ciabatta bread, split horizontally
1/4 pound Fontina, sliced
1/3 cup (packed) coarsely chopped arugula leaves


Preheat oven broiler for 5 minutes.

Brush both sides of London broil with olive oil and season with salt and pepper. Place the steak on a broiler pan and broil about 4-inches from the heat source, about 5 minutes per side. Lay the portobellos and onions in a single layer on a sheet pan lined with aluminum foil. Drizzle with oil and vinegar then put in the oven and roast for 10 minutes. Remove the steak to a cutting board. Let rest for 5 minutes then slice the steak thinly against the grain.

In a small bowl, combine mayonnaise, horseradish, parsley, and lemon juice. Spread mayonnaise mixture on both sides of the split ciabatta. Lay several slices of steak on the bread and mound with a bit of mushrooms and onions. Cover with a couple of slices of cheese. Garnish with arugula, and serve.

Thank you Penelope!  I think today's review was a great one and must try.
