1 cup finely shredded Monterey Jack cheese
1 can (4 ounces) chopped green chillies
1 can (2 ¼ ounces) sliced ripe olives, diced
¼ cup prepared zesty Italian salad dressing

In a bowl, combine the first six ingredients; mix well. Cover and refrigerate for at least 1 hour. Serve with tortilla chips. Makes 4 cups.
