I lived in Buenos Aires for seven years and I have had a lot of different chimichurris. Frank's recipe is hands down the best. My husband and I took his virtual class and learned a number of great cooking tips. We have since made Frank's recipe twice and in two different ways (he includes three ways that depend somewhat on the amount of time you have before you plan to eat it). Even the quick version was delicious and I have a jar of Frank's chimichurri sitting on my kitchen counter right now, just soaking up flavor for the next time we grill. Excellent class. Highly recommended!
