Combine parmesan, anchovies, and garlic and make a thick paste. Once combined add in egg yolk & mustard - whisk to combine.
Once combined slowly add in olive oil while whisking. When it comes to dressing it’s all about the look and taste so add until you reach your desired dressing consistency.
Add a tablespoon of red wine vinegar and a couple dashes of Tabasco.
Toss in your favourite greens, mix, and serve with homemade croutons!
