Combine first 2 ingredients; simmer 15 minutes. Cool sauce. Preheat the broiler. Place the English muffin halves cut side up onto a baking sheet. Spoon Mama Mia Marinara Sauce on each one. (Reserve any remaining marinara sauce for other use.) Cut the string cheese into pieces about the same width of the English muffins and then into matchstick slices. Place two olive slices on top of each muffin; arrange string cheese above and below olives to resemble a mummy. Broil 2-3 minutes or until cheese is melted and muffins are browned on the edges. Makes 6-8 servings.
