In a 2-quart saucepan: Prepare 4 cups INSTANT MASHED potatoes following package directions and using the vegetable liquors as part of the required liquid.
In a large skillet:
Cut 3 lbs. FILET MIGNON (or any steak) in a 2 x 1/2 x 1/2-inch strips. Sauté in 4 oz. margarine OR oil, until lightly browned. Remove the steak from the skillet. Blend in 6 Tbs. flour to make a roux. Add 2 cups Onion SOUP made from a packaged mix and cook to medium-sauce consistency. Correct the Seasoning with salt, pepper, and a little Tabasco. Return the steak to the sauce. Make a large mound (about 1 cup) of Irio in center of dinner plate. Form a hole in the center about 2 inches in diameter. Fill the hole with ½ cup of the sautéed steak and gravy. Smooth around edges of the Irio so it looks like a volcano.
