The temperatures are warming up and shortly summer will be here. For me, that means enjoying recipes that can be made quickly so I do not have to spend too much time in a hot kitchen. I also prefer to have dishes that are lighter in fare but still filling.

Like more sandwiches, salads, and soups. I know what you are probably thinking and that is soups are usually hot, so why would I want to have a hot soup during the warmer months. Well let me share with you that some soups can be served cool, or even chilled, and still be just as flavorful.

Actually today I will share one of my new favorite recipes that is a chilled soup that contains sweet potato, white miso paste, fresh ginger, and green onions. This recipe makes a rich and creamy puree that comes together in minutes and requires only one saucepan and a blender.

I also love making this recipe at the beginning of the week and storing it in the refrigerator to enjoy for lunch with or without a salad and itโ€™s also great for dinner when topped with some grilled shrimp.

It is also really good for an on the go option. I can pour a serving into a small jar with a lid and sip on it in the car. The addition of sweet potato makes it very filling and adds a hint of sweetness and if you have been following me for any amount of time, then you already know that I love sweet potato and even went through a brief phase when I was adding it to everything from Sweet Potato Pound Cake to Sweet Potato Dog Treats for my fur baby to enjoy as a treat.
