Prepare the sauce – In a bowl, mix all the sauce ingredients together.
Cook the noodles – Boil water in a pot and cook the noodles according to the package instructions. While the noodles are cooking, set aside some starchy water. Drain the noodles.
Mix the starchy water into the sauce to loosen it.
Cook the chicken and vegetables – In a pan, heat up some cooking oil with garlic and the white part of the green onions. Add the capsicum and chicken, and cook until the capsicum and chicken are cooked.
Assemble – Reduce the heat to low and transfer the noodles into the pan with the capsicum and chicken. Pour the sauce on top and coat the noodles with the sauce.
Garnish – Sprinkle sesame seeds and the green part of the green onions.
Notes
1. Noodles – I use pre-cooked wheat noodles, but other noodles work too. Wheat noodles are less porous than egg noodles, so they absorb less sauce. Since different types of noodles vary a lot in weight, use 2 servings rather than relying on an exact weight. This can range from around 250 g / 8.8 oz for lighter noodles to 400 g / 14 oz for heavier noodles such as udon.
