Just has this for lunch.
Thinly slice some cabbage and lettuce (how much is up to you). Heat a splash of olive oil in a wide pan and add a couple of finely chopped cloves of garlic. Fry gently for a minute and add the cabbage and lettuce. Add a few chilli flakes if you like a bit of chilli. Give it a good stir and put a lid on. Turn the heat down low so you just hear it cooking.
Cook for 5 minutes or so stirring occasionally and add a drained tin of cannellini beans. Then cook for another 5 to 10 minutes.
Turn the heat off and add some finely chopped parsley and basil and a splash of olive oil. Pour onto a plate or bowl and smother with grated Parmesan cheese.
