Low fat pepper sauce

I was cooking steak for dinner and fancied some pepper sauce,
however I didn't have fresh cream in the fridge so I tried light Philadelphia Cream Cheese. It turned out yum
Half the fat content and I only used
3 ingredients what more could you ask for?
Easy, cheap and low fat.
Here's how I did it.
