Shred the red cabbage and set aside
Bring the water to a boil and add the shredded the cabbage
Bring this to a rolling boil and the colour from the purple cabbage will leach into the pasta and make it quite deep purple- blue
remove the cabbage bits and add salt to the liquid.
As it boils add the spaghetti and cook till aldente
Heat a pan and add the olive oil
Add the crushed garlic and quickly toss in the cooked pasta in the oil.
Toss in the parmesan and the parsley and serve with lemon wedges.
Before you eat, squeeze the lemon n the pasta and see them change to a beautiful deep pink colour.
