re: Grilled tuna app and steak chimichurri (with pics)

No pesto on steak. Chimichurri sauce. Both pesto and chimuchurri have basil and olive oil. Whereas pesto has garlic, pine nuts, and parmesan cheese, the chimichurri sauce has parsley, oregano, shallots, garlic, lime juice, and red wine vinegar.

Pesto is much thicker than chimichurri, which has more liquid.

ETA: I marinate the steak in chimichurri sauce, but hold some in reserve to spoon over the top of the steak just before I serve it. It is very flavorful and gives the steak a little tang...
