Empty the can of scungilli into a strainer and rinse well with very hot water for 2 minutes.
Chop up the scungilli into small pieces with scissors or a knife.
In a large sauté pan over medium heat, heat the olive oil until glistening and sauté the garlic until golden and fragrant, then add the red pepper flakes and salt to taste. Stir until incorporated. Add the lemon and white wine and lower to simmer until the wine is reduced, about 2 minutes. After reduced a bit, add the tomato paste and stir. Lastly, add the scungilli, stirring occasionally, for about 2 minutes. Be careful not to overcook that scungilli as it has the tendency to get rubbery. It is already fully cooked in the can so this is just reheating it and marrying it with the sauce.
Bring pot of salted water to boil and boil pasta until one minute less than al dente. Reserve one cup of salted pasta water.
Transfer the pasta into the sauce, mixing well while simultaneously adding pasta water a little at a time. Garnish with parsley and serve with extra red pepper, if desired.
