1Slice the sausages into bite-sized pieces.
Beat the eggs in a bowl and set aside.
Heat 1 tablespoon of oil in a large frying pan or wok over medium-high heat.
Add the sausage pieces to the pan and cook until browned and cooked through, about 5-7 minutes.
Remove the sausages from the pan and set aside.
In the same pan, add the remaining 1 tablespoon of oil.
Add the beaten eggs and scramble until just set, then remove from the pan and set aside with the sausages.
Add the chopped tomato to the pan and cook for 2-3 minutes until softened.
In a small bowl, mix the soy sauce, oyster sauce, cornflour, and salt with a little water to make a sauce.
Return the sausages and eggs to the pan, then pour the sauce over the top.
Stir-fry everything together for another 2-3 minutes until well combined and heated through.
Sprinkle with chilli powder and serve hot.
