Steps
1. Preheat your oven to 400°F (200°C).
2. In a bowl, toss the diced potatoes with olive oil, paprika, salt, and pepper.
3. Spread the potatoes on a baking sheet and roast for 20 minutes, stirring halfway through.
4. Meanwhile, season the fish fillet with salt and pepper.
5. In a non-stick skillet, sauté the chopped onions until translucent, about 3-4 minutes.
6. Add the fish fillet to the skillet and cook for about 3-4 minutes on each side, or until cooked through and flaky.
7. Serve the crispy fish alongside the roasted potatoes and enjoy with a cup of brewed green tea.
