Spray each tortilla front and back with olive oil spray or brush olive oil onto each tortilla.
Stack together and cut into 8 triangles, set aside.
In a separate bowl mix onion seasoning with parmesan cheese, add tortilla triangles, and toss.
Place tortillas on a parchment-lined cookie sheet and sprinkle the remaining seasoning on top.
Bake in a 350* oven for 12-15 mins. Keep an eye on them, the edges should be just golden.
