Heat 1 tablespoon oil in a large nonstick skillet over medium-high heat.
Add onion and cinnamon sticks; saut 5 minutes or until lightly browned. Stir in rice, and saut 1 minute. Stir in remaining 1 1/2 teaspoons oil, tomato, salt, and broth. Bring to a boil; cover, reduce heat, and simmer 15 minutes or until rice is tender and liquid is absorbed.
