Light and Creamy Zucchini Mint Soup with a Pistachio Crunch

This is a light, creamy green soup that feels fresh but still comforting. The zucchini, fennel, and celery cook down until soft, then blend into a silky bowl with a little richness from cashews. The pistachio mint topping makes it feel pretty, bright, and a bit restaurant at home without making the recipe complicated.
