Step 1

Add the sesame oil and sriracha to a large stockpot and bring to a simmer over medium-heat. Add the onion and tomato and cook for 4 minutes, stirring occasionally. Add the ginger, garlic, and seasonings; cook for 2 minutes or until fragrant. Add 2 cups of water and transfer mixture to a blender or food processor and pulse until smooth. Return mixture to the pot and add the broth.

Step 2

Bring to a simmer; add soy sauce and vinegar (if using), and simmer for 8-10 minutes. Taste and adjust seasonings as needed.

Step 3

Add the ramen noodles to the broth and simmer for an additional 2-3 minutes, or until the noodles have softened. Remove pan from heat, ladle soup into bowls, and top with scallions, cilantro, and eggs (if using). Enjoy!
