In a large skillet, cook the beef, 3 tablespoons onion, 2 tablespoons red pepper and 1 tablespoon green pepper over medium heat until meat is no longer pink; drain. Stir in the nacho cheese, salsa sauce, 3 tablespoons ripe olives, 2 tablespoons jalapeno pickle, oregano and pepper. Bring to a boil. Reduce heat; simmer, uncovered, for 5 minutes.
Transfer to a serving dish. Top with the cheese, sour cream and parsley; sprinkle with the remaining onion, peppers and olives. Serve with tortilla chips.
