30 min chimichurri flank steak grilled dinner high protein low carb serves 4 summer grilling

The first time I made chimichurri, I thought, “Why haven’t I been putting this on everything?” It's fresh, tangy, and turns a simple steak into something crave-worthy. Now, whenever the grill’s on, this flank steak and chimichurri combo is my go-to — quick enough for a Tuesday, impressive enough for guests.
