Preheat oven to 425?, or whatever temperature you are cooking your fishsticks at. On a large baking sheet, place as many of the tortillas as will fit. Spray liberally with oil, then flip and spray the other sides. Bake for 3-4 minutes, then remove them from the oven and flip them over using tongs. Bake for another 3-4 minutes until they are as crispy as you want them. It may take a couple batches to get all the tortillas done. The good news is you can do it at the same time your fishsticks are baking.
Place the cabbage in a bowl and sprinkle with lime juice and salt. Toss. For this step you can use fresh lime juice or the refrigerated kind.
