To make the marinade, mix all the ingredients down to the Tofu in a bowl.
Then add the tofu cubes, mix in and marinate for 15 minutes.
Heat the oil in a large non-stick frying pan or wok over a medium-high heat.
Stir-fry the broccoli and carrot slices for 2 minutes.
Add the tofu and its marinade, adding a splash of cold water occasionally to make sure it doesn't stick.
Cook for 4–5 minutes, or until the tofu is hot and the sauce is thickened and glossy, stirring regularly.
Serve with freshly cooked rice.
