Tips
Let steak rest for at least 5 minutes after cooking to ensure juices redistribute and meat stays tender when sliced.
Start with half the hot sauce in the pan sauce and taste before adding more to control the heat level.
Cut vegetables into uniform 1/2-inch pieces to ensure even roasting and proper texture in the jumble.
Good to Know
Refrigerate leftovers up to 3 days. Store steak and vegetables separately to maintain textures.
Sweet potato and poblano jumble can be roasted up to 2 hours ahead and reheated before serving.
Serve immediately while steak is warm. Provide lime wedges on the side for guests to add fresh citrus.
Common Mistakes
