01 - Preheat oven to 375°F and line a baking sheet with parchment paper.
02 - Arrange fish fillets on the prepared tray. Drizzle with olive oil, then season with salt, pepper, and smoked paprika. Bake for 12-15 minutes until fish flakes easily with a fork. Set aside and break into large chunks.
03 - Heat a large nonstick skillet over medium heat with a splash of olive oil. Add diced potatoes and cook, stirring occasionally, for 10-12 minutes until golden and beginning to soften.
04 - Stir in diced onion and bell pepper. Season lightly with salt and pepper. Cook for 6-8 minutes until vegetables are softened and lightly caramelized.
05 - Fold in chopped spinach and cook for 1-2 minutes until just wilted.
06 - Gently incorporate baked fish chunks and sliced chives. Cook for 1-2 minutes to heat through. Adjust seasoning as needed.
07 - Create four wells in the hash and crack an egg into each. Cover skillet and reduce heat to low. Cook for 4-5 minutes until eggs reach desired doneness.
08 - Serve immediately, garnished with additional chives and accompanied by hot sauce or lemon wedges if preferred.
