Remove the casing from the salami then slice about 1/2cm thick.
Heat oil in a large, deep frypan over medium high heat.
Add half the salami and cook, moving around the pan and flipping occasionally, for 3-4 minutes until they start to caramelise and crisp a little.
Using a slotted spoon remove from the pan.
Repeat with remaining salami and leave the oil in the pan after removing the salami.
Add the garlic to the oil and cook for 1 minute then add the cherry tomatoes, season with salt and the pepper and cook for a further 1 minute then add the passata, handful of basil leaves and return the salami to the pan.
Bring to a simmer, reduce heat to medium and cook for 10 minutes until the sauce has reduced and thickened.
Meanwhile, bring a saucepan of salted water to the boil then add the pasta and cook for 2 minutes less than the packet instructions.
Drain and reserve 1 cup (250ml) pasta water. Add the pasta into the tomato sauce with a little of the pasta water then simmer in the sauce for a minute and toss through the parmesan to combine into the sauce.
