Green oil/herb dipping sauce at Magnus in Madison

Has anyone ever seen a recipe for this stuff?

Thanks in advance

As I recall, it's a version of chimichurri that's a heavier on parsley/oregano than cilantro.

It was chimichurresque, though I thought I tasted dill and fennel (6 years after the OP). Magnus is closed now but the chef is still in Madison, at 43 North. Dunno if the sauce went with him.

It sounds like a green oil at Grecco's in the St. Croix Falls, WI. Watch this Video and he talks about what green oil is. http://youtu.be/Zpc4O90A1uQ
