Note
1. Place the oil in a pan over medium heat.
2. Pour the can of plum tomatoes into a bowl and use a masher or fork to break them apart and crush them down.
3. Add all the remaining ingredients, then simmer on low heat for 20 minutes, or until the flavour has deepened and the sauce has thickened slightly.
4. This sauce can be used straight away, or placed in an airtight container and stored in the fridge for up to a week, ready to be used as required.
