Preheat oven to 430°F or 220°C.
Add all potatoes, bell pepper, onion, and herbs to a baking sheet, drizzle with a little oil and toss to coat. Roast for 20-25 minutes or until potatoes are fork tender.
Meanwhile, combine all salsa ingredients, drizzle with a little oil. Gently mix to combine. Set aside in the fridge.
If chicken breast is in one piece, cut horizontally to make 1 piece each.
Pile the shredded cheese on a cutting board or plate. Season chicken breasts with black pepper. Press the breasts firmly into the cheese. Coat both sides of breasts with as much cheese as possible.
Heat a large skillet over medium-high heat. The pan must be scorching when the chicken is added. Add cooking oil to the skillet. Set breasts into the skillet and cook 5-7 minutes on each side, until cheese forms an even, golden casing around the tender chicken breasts.
Serve with roasted potatoes, veggies and tomato salsa.
