Add the corn flour to a plate and toss the beef strips until evenly coated. Shake off the excess.
Heat olive oil in a fry pan and cook the beef for 5 minutes until cooked through, then set aside on a plate.
Using the same fry pan, add the ginger, garlic and chilli and cook for 1 minute. Add the tamari, coconut sugar and water. Bring the sauce to a boil, then reduce the heat and simmer until thickened.
Meanwhile, place frozen Birds Eye Cauliflower & Broccoli Rice in a microwave safe dish. Cook uncovered on HIGH for 5 minutes, stirring halfway then transfer to a plate.
Add the spring onion and beef back into the pan with the sauce. Simmer for 2 minutes then serve with the rice and broccoli.
