Add one tablespoon of olive oil into a large pot. Add in chopped onion and garlic and sauté over medium heat until translucent.
Add frozen green peas, water, and vegetable stock cube to the pot and bring to a boil over high heat. Once boiling, reduce the heat and simmer until peas are tender, for 5-10 minutes.
Add coconut milk and chopped cilantro and simmer for a few more minutes.
Season with salt and black pepper to taste.
Use an immersion blender to blend the soup, or if using a high-speed blender transfer the soup to a blender and blend until smooth and creamy.
Transfer to bowls. Top with coconut milk, green peas, and fresh cilantro.
Notes
Make sure to blend until creamy. If you don't have an immersion blender use a regular blender.
