Preheat the oven to 200°C (400°F) or heat oil in a frying pan to shallow fry the crispy chicken.

Coat chicken breasts in breadcrumbs or your favorite crispy coating.

Cook the chicken breasts in the oven for 12-15 minutes or fry until golden brown and cooked through.

While the chicken cooks, slice the sandwich buns in half and prepare the cheese by grating or slicing.

Once the chicken is ready, assemble the sandwich by placing a handful of mixed greens on the bottom half of the bun.

Place the crispy chicken breast on top of the greens and add cheese shavings on top.

Close the sandwich with the top bun and serve immediately.
