I use a food processor - its fast and so easy to clean but you can chop all by hand and still perfect.

Peel the Beetroot and chop off the bottom root then slice in half. Then Grate in Processor. Transfer to a large pot with 2 Tbsp of Olive oil and cook on medium for 7-10 mins until soften.

Once Beetroots soft add onion and turn up heat for 2 mins then add carrots and potatos and stock. Reduce to medium Cook with lid for about 15 mins until all soften.
