I make mine with a box of small shells cooked in salty water. Drain and rinse. Dump into a large bowl. Add two large chopped tomatoes and one large chopped green bell pepper. Cook 1 lb. of bacon in microwave, crumble and add to bowl. Add salt to taste and lots of black pepper. Stir in Miracle Whip until everything is coated to your liking. Let marinate for at least 2 hours.
My family loves this, 'specially with fresh garden tomatoes. It keeps well in the fridge IF it lasts that long.
