Mix the breadcrumbs, butter, capers, lemon and herbs together and season to taste, then set aside.
Heat a few tablespoons of oil in 2 non-stick frying pans and fry the eggs separately over a low heat for 3-4 minutes, seasoning the white as they are cooking.
Flip the eggs over, season and cook for another minute then slide onto warm serving plates and scatter the crust on top.
