First, check to see if you need to soak your rice noodles in water for a couple of hours. I have found that some packages of rice noodles want you to and others don't. Start soaking your rice noodles at least one and a half hours prior to cooking if your package calls for it. Otherwise, you won't start with your rice noodles until later.
Heat the avocado oil in a large pot on medium-high heat.
Add the onion and cook on medium heat for 2-3 minutes until translucent. Next, add the garlic and ginger and cook for another minute.
Add the red curry paste, curry powder, turmeric powder, vegetable broth, coconut milk, salt, and pepper. Bring to a boil stirring everything together, then lower the heat to medium-low and let simmer for 5 minutes.
Next, add in the soy sauce, coconut sugar, and lime juice and stir together. Reduce heat to low and let the soup simmer for another 5 minutes.
While the soup is simmering, cook the rice noodles according to the package directions.
When the rice noodles are finished cooking, add them to the soup.
