What can I use instead of white wine?
You could add a little bit of water instead.

I based my chimichurri around this recipe from Cafe Delites. Chimichurri is an herb sauce or table condiment originating in Argentina and Uruguay – here’s more about its history! Also worth noting that using cilantro in place of parsley (as I did here) is not traditional, but I like it as summery way to mix up the flavor profile.
These Grilled Chimichurri Portobellos are OUT OF THIS WORLD. Marinated in a punchy and vibrant chimichurri before heading to the grill, then served on top of a mountain of creamy goat cheese mashed potatoes.
