Step 1

Bring a medium-sized pot of water to a boil. Add the soba noodles and cook for half the recommended cooking time (usually 2 minutes) then drain and rinse well under cold water. You will want them to be firm and a little undercooked as they will cook more in the frying pan.

Step 2

Stir the sauce ingredients in a small bowl.

Step 3

Heat the oil in a large frying pan or wok over medium-high heat. Add the onion, carrot, and peppers and stir-fry for 2 minutes.

Step 4

Add the partially cooked soba noodles and the sauce to the frying pan with the peppers and toss to coat. Toss gently until the noodles have been reheated and are fully cooked, about 2 minutes. Stir in the cilantro, green onions, and sesame seeds.
