Ingredients for Sheet-pan steak fajitas

10 ml chili powder
10 ml ground coriander
10 ml ground cumin
10 ml reduced-salt salt
1 large red onion, halved, sliced into 0.5 cm strips

How to make Sheet-pan steak fajitas
Place the racks in the top and lower thirds of the oven. Preheat the grill to a high setting. Position an 18 x 33 cm rimmed baking tray on the top rack.
Stir together the oil, chilli powder, coriander, cumin, and salt in a small bowl. Transfer half of the mixture to a large bowl and set the remaining oil mixture aside. Add the onion and peppers to the large bowl, then toss to combine.
Carefully remove the hot baking tray from the oven. Transfer the vegetable mixture to the tray and spread it out in a single layer; reserve the bowl for later. Grill the vegetables until they begin to brown and soften, about 5 minutes.
In the reserved bowl, toss the steak with the reserved oil mixture. Push the vegetable mixture to one side of the baking tray and arrange the steak in an even layer on the other side. Grill until the steak is browned and cooked through, about 5 minutes.
Meanwhile, wrap the tortillas in foil and place them on another rimmed baking tray. Bake on the lower rack until warmed through, about 5 minutes.
Serve the steak mixture with the warm tortillas, sour cream, lime wedges, and hot sauce on the side.
