Fry the vegetables in a pan with the olive oil for a few minutes. Add the coconut milk and water. Allow the mixture to simmer until the vegetables are soft. Mash the soup using a hand blender and add the juice from the lemon, salt and pepper to taste.
While the vegetables are cooking, mix the ground beef, eggs, red curry paste and cheese together. Roll out the meatballs and cook them in the soup for 8-10 minutes.
