In the pressure cooker, put oil and fry the pepperoni.
When the pepperoni is almost fried, add the onion and fry until wilted.
After adding the tomato sauce, mix, add a pinch of salt.
Add the pasta, I like the short screw or shell cuts...
Add the water to cover, but without exaggeration, close the pan.
When the pan starts to sizzle, count 6/7 minutes (may vary from stove to stove).
After the cooking time, open the pan, adjust the salt, add the cream, mix well, add the green smell and if you want to increase, you can add cheese or curd and serve hot.
