Buy a big swede, prep it all for cooking and chuck it all in a pan and cook. After 5 mins or so take out and cool what you don't need that day and then freeze it for when you feel the need for swede. Bung into boiling water and enjoy.
I adore swede - one of my favourite vegetables. had it yesterday with our Sunday roast - yummy! But agree about cutting them - I once got a knive completely stuck halfway through one!
