I've made that! It's so good. Steak with chimichurri is the best. Also you can dip just French bread into it. It's good on all types of potatoes and veggies. It's pretty versatile, I've never had it on chicken but seeing you can do it. I bet it would be good with shrimp.
There's this insanely good Argentinian dish, like a steak with ham and cheese, lemme see if I can find it... Argentinian steak milanese napolitana.
Argentina's ultimate comfort food—a breaded beef cutlet topped with ham, tomato sauce, and melted mozzarella. A perfect hybrid of Italian and Argentine cuisine that appears on every neighborhood menu.

It's like Argentinian steak parmagiana.
Those don't recommend the chimi with it, but we used it when we made it for dipping. (I don't think ? the second recipe includes the ham, either.)
