Mix up the spices and add to a medium size sealable bag.
Slice the skirt steak against the grain into thin strips and place into baggy with the dry spices. Shake to coat meat and then add the remaining marinade ingredients. Leave at room temp for 30 minutes or refrigerate for 4 hours or overnight.
Dump the steak and the marinade into the inner pot. Add 1 cup of beef stock. Set the pressure on high for 10 minutes. Allow the Ninja Foodi to release it's pressure for 10 minutes then immediately release the remaining pressure.
Put the rack in the high position and lay the corn tortillas over 2 rungs in the rack. Spritzing with oil will help them be more pliable. Turn the broil on for 3 minutes or until they become warm and slightly crispy.
Double the corn tortillas and stuff with carne asada meat and top with crumbled cheese, cilantro, onion, and sliced radishes. Serve & Enjoy!
