I always wonder what unhealthy ingredients restaurants add to common dishes to make them taste so good.   One common and favorite dish of mine is pasta with pesto sauce.  Every time I eat it, I can’t help but feel guilty because it probably wasn’t good for my health.  I decided to make the pesto sauce myself.  I Googled the recipe, found one that looked authentic and was simple enough to follow.  I bought the pine nuts, basil, Romano Pecorino cheese, and Parmesan cheese.  I already had the olive oil, salt and black pepper.  The end result?  It was absolutely delicious.
