Add ground sirloin and spices. Cook 8-10 minutes or until meat is browned, stirring occasionally with a wooden spoon to break up meat. Check for seasoning and add salt and pepper to taste. Stir in toasted pine nuts and set aside.
Toasting the Pine Nuts:
Preheat oven to 350 degrees. On a small cookie sheet place raw pine nuts and cook for 5-7 minutes or until they are at a light brown in color. Keep a careful eye on them as they can burn quickly.
