In a 4-qt. saucepan, heat the oil over medium heat. Saute the pasta until slightly browned. Keep stirring constantly to brown all sides. About 5 minutes.
Add the onions and saute for another 1 to 2 minutes until soft.
Add the tomato sauce and stir for about a minute or so. Be careful that if the pot it's too hot, the tomato sauce will splatter.
Add the broth, the bullion, cilantro, pepper & salt.
Bring to a boil, and reduce heat to medium low; cover with a lid (leaving it slightly open) and simmer until the noodles are tender, about 15 to 20 minutes.
