Japanese Vegetarian Dishes: Cold Green Tea Soba Noodles


Soba noodles are one the most popular dishes in Japanese cuisine, yet tea soba noodles or “cha soba” is totally a brand-new experience. It is still thin Japanese soba noodle but infused with green tea. As stated by thespruceEats.com, it’s the subtle flavor of green tea that takes this dish to another level. During summer-time in Japan as the weather is hot and humid, a bowl of chilled cha soba is super-duper refreshing. What is the most special thing about this dish? It’s vegan!

Let’s discover how to prepare it at home for your family. The recipe is inspired by thespruceEats.com
