Preheat your oven and cook the fish sticks according to the package instructions until they are golden and crispy.
While the fish sticks are baking, prepare the toppings. In a small bowl, mix the sour cream, lime juice, chili powder, and a pinch of salt and pepper to create a zesty sauce.
Warm the corn tortillas in a dry skillet over medium heat for about 30 seconds on each side until pliable.
Once the fish sticks are done, assemble the tacos by placing 2-3 fish sticks on each tortilla.
Top with shredded cabbage, avocado slices, diced tomatoes, and a sprinkle of cilantro.
Drizzle the zesty sauce over the top of each taco.
Serve immediately and enjoy your crispy fish stick tacos!
