Precooked thick wheat noodles are typically found in the refrigerated section of the supermarket. Preparing soba noodles is a worthy substitute.
Loosen the precooked noodles by soaking in a bowl of hot water for 2-3 minutes, then drain and set aside.
Mix together the soy sauce, oyster sauce, sesame oil and 2 Tbsp water in a bowl.
Heat a wok or large frying pan over a high heat, add the oil and stir-fry the carrot and broccoli for 2 minutes.
Add the tofu and stir-fry for 4 minutes.
Add the garlic and ginger and stir-fry for a minute.
Stir through the noodles and then add the sauce mixture and cashews and mix until thoroughly combined and heated through.
