Combine green olives, black olives, 1/2 teaspoon oregano, and oil in a small bowl. Set aside. Beat together cream cheese, pinch of oregano, and pinch of garlic salt. Spread the mixture onto tortillas. Sprinkle olive mixture over the top of each. Starting at the top of each tortilla and about 1/8 inch down place a slice of ham, provolone, salami, and mozzarella slightly overlapping each slice.
Roll the tortillas up and wrap in foil. Chill for at least 2 hours.
Remove the foil and slice on a 45 degree angle into 1-inch pieces.
