What exactly is chimichurri sauce?
It is a infamous green sauce that originated in Argentina and has become very popular in many South American countries, such as Brazil, Uruguay, and Paraguay. It’s not cooked, so it is used as a side sauce (or condiment) as well as an ingredient in certain recipes. In our case, we are also using it as a marinade. It is said to be as popular in South America, as ketchup is in North America, and soon you’ll see why!
It’s a light and refreshing sauce with a citrus base, either vinegar or lemon juice lots of fresh herbs, olive oil, garlic, and red pepper flakes for spice. Of course, everyone has adapted ingredients to come up with their own version, but it always starts with a parsley base.

Definitely. They are cut from different areas, so they’re not the same, however, they have enough similarities that you can use one in place of another. Skirt steak is another affordable, tasty cut of meat that can be tougher and will need to be tenderized. Depending on the thickness, you may need to adjust how long it sears.
Flank steak has very visible lines that run across the entire cut of beef in one direction. Cutting against the grain means using a sharp knife to cut thin slices in the opposite direction.
