Get your prep done before you start cooking. Remove casings from sausages. Finely chop the onion and mince the garlic.
Heat oil and butter over medium in a large skillet. Add sausages, break up into pieces and cook until brown for about 3 minutes. Add garlic and onion, cook for 2 minutes. Stir in salt, pepper, basil and chili flakes.
Add puréed tomatoes, bring to a boil and simmer for about 10 minutes over low.
In the meantime, add penne to the pot with boiling water and cook until al dente. Scoop up ½ cup cooking water, then drain the penne.
When ready, add Parmesan and stir until combined. Add peas and a generous splash of cooking water, simmer for 1 minute. Toss with penne and stir until glossy. Finish off with freshly cracked black pepper, some extra chili flakes and parsley. Enjoy!
