This will finish cooking the steak to about a medium to medium-rare temperature and soften the veggies. Remove both the foil packet and the steak from the grill and let cool for a few minutes.

6 Make the Dad Add Lime Sour Cream (optional): In a small bowl, combine sour cream, zest, juice from 1 lime, cumin, and salt. Serve alongside the fajitas.

7 Slice the steak: Slice the steak thinly against the grain.

8 Serve: You can add the steak to the veggies and serve the fajitas right out of the foil packet alongside a stack of flour tortillas. The foil should be strong enough, but if yours seems unstable, you can also transfer the ingredients to a serving platter.

SUGGESTIONS AND SUBSTITUTIONS
The seafood rub I use has cayenne pepper in it. You can adjust how spicy you like your shrimp by reducing (or increasing) the amount of cayenne. For a super spicy twist, serve this with hot sauce!
