Heat your olive oil and fry the garlic gently for 1-2 minutes being careful not to burn it
Add the tinned tomatoes, herbs and sugar and bring to the boil. I usually add a little water to the tin to clean it out and add this to the saucepan.
Simmer for 20-25 minutes making sure to stir every now and then
Puree the sauce using a hand blender until smooth
Season with salt and black pepper. The quantities will depend on your taste buds.
