Clean seeds from cherry peppers (or leave a few for extra kick), pick parsley leaves and discard stems, peel garlic cloves. Finely chop all fresh ingredients.
Combine olive oil, red wine vinegar, dried oregano, salt & pepper in a medium bowl.
Slowly mix in fresh ingredients. Add all of the parsley, but incrementally add in the garlic and cherry pepper, tasting frequently until you get the balance of flavors you desire. (Too much garlic or hot pepper can quickly overpower your chimichurri.)
Once you're happy with the flavor profile, cover your chimichurri and refrigerate for at least 3 hours to allow the flavors to fully blend together.
Finally, put your fresh chimichurri on absolutely everything- beef, pork, fish, chicken, or veggies. Enjoy!
