Soak the rice in hot water for 10 minutes and drain. In a food processor or blender combine the tomatoes, garlic, ½ the onion, cumin, and paprika and blend well. Finely chop the celery, pepper and the remainder of the onion. In a wok or large skillet, heat 2 tablespoons of the oil on medium heat. Add the rice and cook for 5 minutes, constantly stirring (you don’t want the rice to stick). Add 90% of the tomato mixture and cook until the liquid is absorbed, constantly stirring (approximately 8 minutes). Add the veggie broth, and bring to a boil. Reduce heat to low, cover and simmer for 30 minutes.
