In a large, wide-bottomed pot or a dutch oven, sauté red peppers, carrots, garlic, and green onions in sesame oil over medium heat until soft. Remove from pot and set aside.
In the same pot, boil vegetable broth, then drop in noodles. Cook over high heat until they soften and break apart.
Then pour vegetables back in. Stir in red curry paste, reduce heat to medium, and let simmer for 20 minutes. If your liquid begins to boil, turn heat down to medium-low.
When fully cooked, serve in a bowl and top with additional sliced green onions.

Notes
Red curry paste can usually be found in the Asian food aisle of your grocery store.
Tomato paste can be substituted for the red curry paste.
Low sodium vegetable broth is a good option here if you need to control the sodium.
