Because in our humble opinions, nothing can't be improved by the addition of Caesar sauce.
Place the egg yolks, garlic, mustard and vinegar in a sturdy bowl and whisk to combine. Slowly pour in the oil, adding more if you need to, until you have a smooth emulsified sauce.
Fry the burger pattys. Meanwhile, slice the lettuce and dress with a few blobs of the Caesar and the chives.
Melt the cheese on the patties, toast the brioche buns and build the burgers. Slice them in half and serve in the rest of the caesar sauce along with the fries and more parmesan on top!
