Add 3 Tablespoons of Olive Oil into a wok or large frying pan.
Add in garlic slices and peperoncino. Then place the wok on medium-heat and wait until the ingredients sizzle in the oil.
Once the edges of the garlic start to brown, add in soy sauce. Then immediately add in the spinach... to prevent oil from splattering out!
Now lower the heat to a LOW. Stir-fry the spinach around for 10 seconds... or until the spinach starts to sweat.
Now, quickly add in the anchovy filets. Followed by Salt (3 big pinches) and Black pepper (4-5 cracks). Give everything a good stir for 10 seconds.
Now add the penne (200g). Along with some* of the residual pasta water (*note: don't have to add everything in)
Raise to a HIGH heat and stir-fry everything together for 30-40 seconds.
Turn off heat. Give it a quick taste - add pinch of salt if slightly bland..
Plate and enjoy!! You're going to love it.
