Fast and Easy Noodle Soup

Most noodles take about 12-minutes to cook, which isn’t long, and also need to be cooked in a second pot. But a healthier, gluten-free noodle cooks in half the time and can be added directly to the soup. 

Noodles cook directly in the broth in 5-minutes.

These sweet potato buckwheat noodles are not just flour and water, like most noodles, but have a slightly sweet flavor and protein rich buckwheat, which is a whole grain similar to quinoa. 

Vegan Buckwheat Japanese-style Noodle Soup

This noodle soup is just pure vegan goodness. No gluten, no dairy, no meat and no fish. The flavors are derived from the vegetables, ginger, garlic and toasted sesame seed oil. 

Since this bowl of warm goodness is created for those meals when eating alone, by all means, swap out for some of the ingredients you might already have in your fridge.

Vegan Soup

Some of the best flavored soup stock comes from vegetables and herbs alone. The addition of meat or seafood, while adding their own flavor, add fat. 

Fat, or should we say oil, comes also from seeds and nuts. In this soup the toasted sesame seed oil adds both an element of fat and loads of flavor. 

Caramelizing the spring onions and garlic until lightly toasted also bring another layer of flavor to the soup broth, so do take a few minutes to brown these first before layering on the remaining flavors.
