To a large pot add the vegetable oil and heat over medium heat.
1 Tbsp vegetable oil
Add the fideo and cook for one minute stirring constantly.
7 oz fideo noodles
Add onions and carrots and lower heat and continue cooking, stirring to prevent the fideo from burning. Sauté until the fideo is toasted and golden brown. (Do not leave pot alone at this stage as the fideo changes color quickly and might burn).
¼ cup chopped white or yellow onion, 2 small carrots
Add the broth, tomato sauce, bullion, cilantro, salt & pepper. Stir to incorporate everything together.
6 cups vegetable broth (see note below) , 8 oz can (about 210 grams) Tomato sauce , 1 Teaspoon better than bullion stock (no chicken base), ¼ cup chopped cilantro, 1 teaspoon kosher salt, ½ teaspoon black pepper
Increase heat to medium-high to bring soup to a boil, then reduce to a simmer, and cook for 10 minutes or until fideo is soft.
Remove pot from heat, and allow soup to rest for another five minutes.
Serve with lime wedges, hot sauce and tortillas on the side.
