In a medium bowl, combine hot sauce, soy sauce, onion powder, dried cilantro, fajita seasoning mix, black pepper, and salt.
Mix all the ingredients together until well combined.
Place steaks in a shallow dish or resealable plastic bag.
Pour the marinade over the steaks, ensuring they are evenly coated.
Cover the dish or seal the bag, and refrigerate for at least 4 hours, or overnight for best flavor.
When ready to cook, remove the steaks from the marinade and discard any excess marinade.
Grill the steaks to your desired level of doneness.

Wine Advice:
The fiery flavors of this spicy Mexican marinade call for a wine that can cool the palate. Try pairing with a crisp and slightly sweet white wine like Riesling or a sparkling Moscato.
