Tsubi Soup Instant Hot & Sour Tomato Soup Cubes — 4-Pack Freeze-Dried, Vegan, Gluten-Free, Ready in 5s

Tsubi Instant Tomato Soup is a freeze-dried, plant-based hot-and-sour tomato broth cube that makes a savory 6oz cup in five seconds with just hot water.

Designed by the same Kyoto artisans behind Tsubi's award-winning instant miso, this Hot & Sour Tomato variety blends freeze-dried tomato, molokhia leaves, okra, carrots and togarashi for a bold, tangy cup that’s ready anywhere. Each individually wrapped cube is shelf-stable for 12 months, soy- and gluten-free, and contains no MSG, artificial colors, preservatives, or seed oils. With 380mg sodium per serving, it’s a lighter instant-soup option compared with typical instant mixes.
