I adapted this recipe from Best of Bridge – I put the egg yolk into the dressing and included some red wine vinegar for zip! The prosciutto is an idea I stole from the Caesar salad our good friends Paul and Shannon serve.
This dressing is great on kale or romaine lettuce. If you use kale, dress half an hour before serving to give it a chance to soak in. Marty and I actually prefer a mix of kale and romaine but if you do that, don't add the romaine until right before you serve it!
