Friday's special soup.
In a large pot, heat a tablespoon of oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes.
Stir in the minced garlic, grated ginger, and chopped lemongrass. Sauté for an additional 2-3 minutes until fragrant.
Add the diced pumpkin to the pot and pour in the vegetable broth. Bring to a boil, then reduce the heat and let it simmer for about 20 minutes or until the pumpkin is tender.
Using an immersion blender, blend the soup until smooth. Alternatively, you can carefully transfer the soup to a blender in batches and blend until smooth.
Return the blended soup to the pot and stir in the coconut milk. Heat through, and season with chili flakes, salt, and black pepper to taste.
Ladle the soup into bowls and garnish with fresh cilantro before serving.
