In a medium pot over medium-high heat, bring 1/2 cup broth to a simmer. Add onion and garlic and cook about 5 minutes or until onion is translucent and tender. Stir in coriander and cinnamon and cook 1 minute. Add bulgur and toast for 30 seconds, stirring constantly. Add the remaining 3-1/2 cups broth and tomatoes with their juices and bring to a boil. Reduce heat to low, cover and simmer 10 to 12 minutes or until bulgur is tender. Stir in lemon juice; garnish with parsley and feta.
