Heat your Blackstone grill to about medium-high heat around 400 degrees. Spread some vegetable oil all over the surface so nothing sticks.

Lay out the steak pieces and onions evenly on the grill. Sprinkle with onion powder, salt, and pepper, then cook them for 4 to 8 minutes on each side until nicely browned and done.

Slide the cooked steak and onions to one edge of the grill. Turn the heat down to medium.

Put the tortillas on the empty part of the grill. Add a layer of shredded mozzarella and Monterey Jack cheeses, then spoon on the steak and onion mix. Top it off with more cheese.

Fold the tortillas in half making a half-moon shape. Let them cook for a minute or two until the bottom turns golden and crispy.

Carefully turn the quesadillas over and cook the other side for another 1 to 2 minutes until golden, watching close so they don’t burn.
