Need: freezer, plastic tubs, big pot.
I fill a five or a seven litre pot with loads of veg, spuds, a few steaks. Boil for half an hour, turn to pulp with a hand blender, and voilÃ:

Or a few kilos of tomatoes, minced meat, carrots and red peppers, and that's spaghetti bolognaise (just add spaghetti).
Or spuds, carrots, leaks, onions, and two or three whole chickens.
Onions, garlic, and broccoli get added to pretty much everything.
All goes into tubs, into the freezer. Take out two tubs each night to thaw.
Point is, I spend a day cooking and I eat clean, non-processed food every day for a month.
