Basil Yogurt Drizzle:
Add the yogurt, basil, and salt to a blender along with ¼ cup water and blend this mixture until it is mostly smooth. If you prefer, you can skip the blender and instead finely chop the basil, then mix it by hand with the yogurt, water and salt until all ingredients are well combined.
Tomato Soup with Rice:
1. Microwave the rice for 2 minutes as per the package instructions, and set aside.
2. Melt the butter in a large pot over medium heat. Then add the onion, garlic, and ½ teaspoon of the salt and cook until the vegetables are tender and fragrant—3-4 minutes.
3. Add the tomato juice, diced tomatoes, remaining 1 teaspoon of salt, and the pepper. Bring the mixture to a simmer and cook until slightly thickened, about 10 minutes. Transfer the soup to a blender and puree it until smooth, then return it to the pot and stir in the rice and cream.
4. To serve, divide the soup into bowls, top with the Basil Yogurt Drizzle, and sprinkle with the basil leaves if desired.
