I guess my use of anchovy paste is the most expected, most common. I try to find healthy alternatives to things I love when it's something that could be really heavy, and not so heart-healthy. I searched for a lite Caesar dressing. I think Caesar salad is the one time I get the whole romaine rather than the hearts, 3 to a package. I found a great recipe, and it's one I'd use for company... they don't need to know it's a healthier version. I generally don't cut corners in the name of 'healthy' for holiday or company meals, but this dressing's a keeper.
This recipe calls for using either the anchovy filets or anchovy paste.
