Per serving
Preheat oven to 200°C (400°F). Line a large baking sheet with parchment paper.
Toss the halved baby potatoes with 1 tsp olive oil, salt, and pepper. Place on one side of the pan and roast for 10 minutes.
While potatoes start, mix panko, parmesan, oregano, garlic powder, lemon zest, and 1 tsp olive oil in a small bowl until it looks like wet sand.
Remove pan from oven. Push potatoes to the side. Add zucchini, cherry tomatoes, and olives to the pan. Place tilapia fillets in the center.
Press the crumb mixture firmly onto the top of each tilapia fillet to form a crust.
Drizzle remaining olive oil over the veggies. Return to oven and bake 10-12 minutes until fish flakes easily and crust is golden.
A complete sheet-pan dinner that tastes like a summer holiday. The crispy parmesan-herb crust transforms simple white fish into something special, while the bursting tomatoes create a natural sauce. 41g protein and ready in just 30 minutes.

Squeeze fresh lemon juice over the fish just before serving.
If your fish fillets are very thin, add them to the pan for only the last 8 minutes to avoid overcooking.
Best eaten immediately for the crunch. Leftovers keep 2 days in the fridge; reheat in an air fryer or oven to restore texture.
