How to Make It
Cook fish sticks according to package directions.
Meanwhile, divide broccoli tops from stalks; finely chop tops. Peel stalks with a vegetable peeler and cut into matchsticks. Place onion, lime juice, and ¾ teaspoon salt in a large bowl. Toss to combine and set aside to marinate, about 10 minutes. Add broccoli tops and stalks, cilantro, and oil and toss to combine.
Whisk sour cream, cumin, and remaining ￼¼ teaspoon salt in a small bowl. Spread tortillas with sour cream mixture. Break up fish sticks and divide among tortillas. Top each taco with broccoli slaw and serve remaining slaw on the side. Serve with lime wedges.
