Simply mix all salad dressing ingredients in a mason jar and set aside on the counter to marinate. Always adjust for taste.
Divide arugula between 4 plates.
Tear your prosciutto into smaller pieces and fry in a skillet for just a couple of seconds per side to make them crispy and set aside on a plate.
In that same skillet, spray with some non-stick or coconut oil spray, place around 1/4 cup of parmesan in warm skillet and spread it out slightly but not leaving any gaps. As it starts to melt you will crack an egg on top of each pile of cheese and then cover that skillet. Cook until the egg is done to your likeness and the cheese is crispy on the bottom.
Top the salad with your crispy prosciutto, frico egg and spoon over some of that lemony Italian vinaigrette.
This also makes a wonder open faced sandwich with some really good ciabatta or focaccia underneath the salad.
