Set pot of water for pasta on stove to boil.
While water is heating, gather all ingredients.
If using, slice sausage into chunks about 1" thick. Add 1 tbsp olive oil to saute pan, preheat, then add sausage. Cook until sausage is cooked through.
If necessary, slice pepperoncini (1/3 cup) and Kalamata Olives (1/2 cup) while sausage is cooking.
Remove sausage and drain the pan, but no need to clean pan. Add 1 tbsp olive oil, garlic (5 cloves minced), red pepper flakes (1/2 tsp or to taste), and anchovy paste (1 tbsp - if using). Stir until garlic is lightly browned, about 1 minute.
At this point your water is probably boiling. Add pasta to water and cook according to package instructions (about 8-9 minutes for buccatini).
Add tomatoes (2 cans) and oregano (1 Tbsp). Bring to a simmer and cook until thickened, about 5 minutes.
Add olives (1/2 cup), pepperoncini (1/3 cup) and capers (3 Tbsp). Stir and let simmer 1 minute
When pasta is done, retain 1/3 cup of the pasta water.
Drain pasta and add to the simmering sauce. Add pasta water 1 Tbsp at a time, as needed, to thin the sauce.
Season with salt and pepper as needed
Top each serving with parsley and grated parmesan. Enjoy!
