Steak Fajitas Foil Packets

All you need to make them is some flour tortillas, sliced top sirloin or beef tenderloin, onion, bell pepper, some fajita seasoning, salt, pepper and olive oil.

We like to place the packets on a baking sheet to prevent the foil packet getting punctured, causing juices to leak. Silicone-coated tongs like these ones are helpful for moving around hot packets too.
