Chimichurri sauce is an Argentinian condiment that is full of fresh, vibrant flavors. It's made with quality olive oil, red pepper flakes, vinegar, and fresh herbs. Making your own chimichurri sauce can be a hassle, especially since most people don't keep fresh parsley, oregano, and cilantro in their home. Fortunately, you can purchase this condiment from a retail chimichurri sauce supplier. If you're new to cooking or simply trying to expand your culinary repertoire, chimichurri sauce is an excellent addition to your pantry.
