Mexican Sopa de Fideo is one of the most traditional soup in Mexico and is usually part of the mid-day meal in Mexican homes and in small restaurants called Fondas.
Place roasted tomatoes, garlic, and onion into a blender. Process until you have a smooth mixture. Strain this mixture using a colander into a bowl and set aside.
Heat oil in a large saucepan over a medium-low heat, and add the fideo noodles (vermicelli noodles.) Fry the noodles slightly, stirring often, until they have a light golden-brown color, 3-4 minutes.
