Notes

If you prefer a smoother soup, you can blend it briefly with an immersion blender before serving.
You can customize this soup with extra garnishes if you like. Try adding chopped fresh cilantro, thin slices of chili for some heat, a squeeze of lemon juice for brightness, or small cucumber cubes for a fresh crunch.
