I'm a huge fan of Chimichurri Sauce, a meat-lovers' green herb sauce from Argentina. It's a mixture of very finely minced parsley, oregano, garlic, oil, vinegar, salt and pepper. I've substituted cilantro for all or part of the parsley (I think it's divine, but I used to despise cilantro's flavor, so I understand if you think that's an awful idea), and some use red chili flakes for the pepper part of the recipe (sometimes I do, sometimes I don't). I make it easy by using garlic powder (and onion powder, if I'm feeling it that day) instead of chopping fresh, although I've done it that way too. I've even gone rogue and added grated parmesan to it on occasion, just for variety.
There are loads of recipes on the internet, but I just think of it as a tiny green salad, and mix to proportions that suit my taste.
