Carne Asada Tacos Prep:
Marinate the Flank Steak

To get a head start on dinner, you can marinate the flank steak earlier in the day or the night before. We recommend letting it sit for at least 4 hours to really soak in the flavor, but if you're short on time, 2 hours will still do in a pinch. Just pop it in the fridge and let the marinade do the work while you prep the rest or go about your day.
