COLD VEGETABLE ROLL

2 lbs potatoes
Boiling salted water
2 tb margarine or butter
warm milk
1 tsp salt
1/4 tsp ground pepper
3 tb olive oil
1 large onion finely chopped
2 garlic cloves crushed
1/2 cup diced cooked carrots
1/2 cup diced green pepper
1/2 cup cooked peas
1/2 cup diced cooked zucchini
1/2 cup shredded Muenster or Mozzarella
Mayonnaise

Cook the potatoes, peel and mash with butter and warm milk. Season with salt and pepper. The potatoes must be smooth and somewhat dry. Spread the potatoes on waxed paper, forming a 9x12 rectangle. Heat the oil in a skillet and sauté the onion, garlic cloves and remove from heat. Add the carrots, green pepper, peas, zucchini and cheese. Toss to mix. Add 2 tb mayonnaise, enough to make the vegetables cling together. Spread the vegetable mixture over the mashed potatoes. Roll up the mashed potatoes, starting al the long side, enclosing the vegetables and using a spatula to loosen from the waxed paper. Place on a serving tray and chill in the refrigerator for at least 1 hour. Serve, sliced.
