Cook the sweetpotato in the microwave and let cool slightly. Then cut it in half lengthwise. Then cut the halves in half lengthwise again. You should have 4 bread like slices now
Cut the tomato and spring onion and mix together in a small bowl with salt and pepper. Set aside for an hour to get a great flavor.
Now layer the tomato mix on the sweetpotato slices and sprinkle/ cover completely with cheese
Now you can microwave or bake the bruschettas in the oven until the cheese is melted
