Carbonara sauce, is really very simple. Most start with the same ingredients: pancetta (Italian bacon), onions, eggs or egg yolk, Parmesan or Parmigiano-Reggiano, and often, heavy cream. Can you say fat and cholesterol! So yet another challenge to healthy eating confronts me. Can I do carbonara in a healthy way? Absolutely! In addition to lightening the ingredients, I added broccoli and mushrooms. I also considered spinach and may well try that next time.
