Preheat oven to 350°F.

Pound steak on each side with a meat mallet, until tender. Season both sides with salt, and pepper if using.

Place 3 tablespoons of mashed potatoes (see below) on one end of each sandwich steak; form potatoes into a neat mound. With clean hands, carefully roll each steak toward you until you have a neatly formed roll ups.

Arrange steak roll ups, seam side down, on a baking pan. Brush each roll up with olive oil.

Bake uncovered for 45 minutes.

Ladle hot vegetable sauce over 4 plates. Place 2 steak roll-ups over each plate of sauce. Serve.

Creamy Mashed Potatoes:

Place cubed potatoes and onion in a 3 or 4 quart pot. Add salted water to cover. Bring to a boil; cook potatoes for 25 minutes, until fork tender. Reserve 2 tablespoons cooking water; set aside.

Drain potatoes. Add oil and reserved cooking water, and season with salt to taste. Mash with a potato masher, until potatoes are smooth. Add the egg, and mash the potatoes once again until very creamy. The egg will cook quickly in the steaming mashed potatoes.
