I like to cook the veggies in a foil packet because you can assemble it in advance and just toss them on a hot grill when you’re ready. You can even make individual foil vegetable packets—spicy for the adults and mild for the kids!
Together with the grilled steak, this meal is so easy and you can feed your family or a few friends without too much work. This also transports beautifully and is great for camping trips.
With that in mind, you can definitely assemble everything up to a day in advance with no worries. Toss the packet and the steak on a hot grill and you will be in really good shape!
To assemble the foil packet two days in advance, follow these steps:
Make the spice mix (you can do this weeks in advance).
Slice peppers and onions, season and wrap them in the foil packet.
Season the steak, cover it, and keep it in the fridge.
Grill when ready!
