Pre-heat the oven to 400°F.
Tear the bread into pieces and place on a baking sheet. Toast the bread until it is deep golden brown, 10 minutes. Transfer to a food processor and coarsely grind into breadcrumbs.
While the bread toasts, pound out the chicken breasts to 1/4-inch thick. Season the chicken with salt and pepper. Coat the chicken with flour and reserve. Beat the egg with splash of water in a shallow dish.
Transfer the breadcrumbs to a plate and season with the herbs and poultry seasoning.
Heat a thin layer of EVOO in a large skillet over medium-high heat.
Coat the chicken in the egg, followed by the breadcrumbs, then add to the pan. Sauté until golden and firm, 3-4 minutes on each side.
