Clean and roughly dice the vegetables. If larger cubes heat the olive oil in a large pan, add the vegetables, season and let simmer for about 8 minutes. Stir in tomato paste. Add water and rice.

Bring everything to the boil briefly and cook on the lowest setting, with the lid closed, for 25 minutes

You do not need to adhere to the prescribed amount of vegetables, you can weigh them in or out.
