Mix the cayenne pepper into the Parmesan cheese.
Heat a small frying pan on a low to medium heat.
Scatter the Parmesan cheese all over the frying pan, covering it with a thin layer.
Cook for 2-3 minutes on each side, then flip over to the other side and cook this for about 2 minutes.
Remove the cooked cheese from the pan and place over a rolling pin (or something circular). Leave to cool.
Remove and voila! A cheesy Taco Shell!
Fill with your choice of vegetables/meat/fish, eat and enjoy!
