1. Bring a saucepan with 1L water to the boil (keep covered).
Heat a large pan with 1 tbsp oil over medium heat. Chop and add onion and celery, cook until softened (see notes).

2. Increase temperature to high, add mince and cook, breaking up any lumps with a wooden spoon. Season with salt and pepper.

3. Dice carrot and courgettes (see notes), add to pan along with mushrooms, rosemary sprigs, tomato sugo and 1 jar water. Semi-cover and bring to the boil. Simmer for 10 minutes.
