Cook the noodles according to package instructions. Then drain and set aside. While the noodles are cooking, peel and grate/mince the garlic and ginger. Slice the spring onions. Steam the vegetables of your choice. In my video I didn't use any vegetables but I suggest using green asparagus, broccoli, or a combination of both called bimi.
In a pan, heat up the sesame oil. Sauté the garlic and the ginger until soft and fragrant. Add the sugar. Where I live, regular white sugar is vegan. You can use any type of sugar you want. Sauté until the sugar is dissolved. Add the sriracha and soy sauce. Turn down the heat to a medium high heat and leave until the sauce becomes sticky. Stir occasionally.
Add the noodles, the spring onions, and steamed vegetables and stir until everything is combined. Taste and adjust. I added in a little more soy sauce and sesame oil.
