Toss the potatoes on a baking sheet with a drizzle of olive oil and season with salt and pepper. Place in the oven and roast for 20-25 minutes, until golden brown.

Heat a drizzle of olive oil in a large pan over medium-high heat. Add the green beans, onion, bell pepper and garlic. Cook, tossing for 7-8 minutes, until softened and slightly blistered. Stir in half the chopped cilantro, season with salt and pepper, and set aside.

In the same pan, heat another drizzle of olive oil over medium-high heat. Season the fish on all sides with the blackening seasoning, salt, and pepper. Add the fish to the pan and cook for 2-3 minutes per side, until cooked through and slightly blackened.
