1. Remove the stems from the tomatoes and place them in a pot along with the water and Kayanoya Original Vegetable Stock Powder (Remove from the packet). Bring to a boil and simmer for 5 minutes.
2. Cook until the tomatoes are soft. Once cooled, blend the mixture and strain it through a fine-mesh sieve.
3. Chill in the refrigerator, then serve in bowls, drizzling with olive oil and sprinkling with black pepper to taste.

Note: For an elegant touch, pour the soup into glasses and garnish with micro tomatoes as desired.
