Grease an ovenproof dish (I use butter but I am sure olive oil could work).
Tear the bread into pieces and put it into a mixer, add the seeds and turn them into rough breadcrumbs.
Add the parmesan, pepper and lemon zest (if using).
Melt the butter.
Add the butter to the breadcrumb mixture and mix well.
Put the chicken breasts in the ovenproof dish and pat the breadcrumb mixture firmly down on top of them, covering all of the flesh.
Bake for 25-30 minutes.
Optional: Once the chicken is cooked take it from the dish and add the lemon juice to the pan, mix well and serve as a side-sauce. This is very strong and not everyone likes it but it works very well with veggies such as broccoli. Use sparingly!
