My husband wrote the below method. I have edited it slightly in italics to be more PG and potentially less offensive!
Remove the 30 layers of cling wrap from the veges the supermarket insists on sticking on to piss you off annoy you. Cut the veges up into perfect 3cm cubes (use a ruler) - honesty just cut them up into rough chunks, they will roast fine without being OCD about it. Toss vegetables and garlic cloves in the olive oil and place on either one large baking tray, or even two trays if needed.
Roast them to within an inch of their little vege lives on rusty trays non stick baking trays (make sure your oven is perfectly clean and has tin foil on the spill trays - yeah, yeah -this is a dig at me because I am a messy cook living with an OCD husband) at 220c for 30-40 mins.
In the mean time, warm up the packet of stock from wollies (the one that your wife has taught you to buy that has no added sugar or other nasties) - not the shit stuff (don't be tight)
Remove baking trays from oven when done and squeeze the garlic out of its papery like case. It should be nice and gooey. Curse like an irish sailor when you try to pry the roasted veges off the non stick (yeah right!, rusty) roasting tray. Admit defeat and scrape the veges off in a big sticky messy lump. Obviously if you have a nice non stick roasting tray you will not have this problem. Fight with husband over the sticky golden crusty bits (hand whacks!)
Throw it all, including the warm stock in the screamer blender with the salt and pepper (heavy on the heart attack(soldiers bolt)).
Blitz till it looks like hot baby poop thick and creamy. Serve with toast dripping in butter spread with avocado or tahini or drizzled with extra virgin olive oil and topped with your favourite soup toppers as mentioned above in the full blog post.
Clean up all the dishes before you eat it as its sucks doing the dishes later - even if you food goes cold. Eat cold dinner. Enjoy your soup whilst hot, dishes can wait.
