leftover roast veg soup — dead simple

Had a load of roast parsnips and carrots from Sunday sitting in the fridge and I cannae stand waste so basically just chucked everything in a pot. Boiled them down with some stock, a bit of ginger, half an onion I found lurking about. Blended it. That's it. Isla had two bowls and called it "orange witch soup" which I'm taking as a five-star review. Mind you Alfie refused to even look at it so, aye. Six years old and already a food critic.
