I'll have to try that out. My current version substitutes mayonnaise in place of the yolk and oil, and just mixes it with lemon juice, dijon, garlic powder, and pepper.
(And customizable - I usually make mine with a little more garlic. This last time I tried making it with a whole-grai. Mustard and the results were delightful.)
It's literally a three minute recipe that I can autopilot.
