would be really intresting to have a chef to cook your food, as well ashave ti work with Pam's Harverstcraft

Already possible with courier.

Sorry I meant to say have them craft the food and ingredients, can the courier do that?

A worker can operate the autocrafting block from automation module, if equipped with a hammer.
A courier can take out the items from the crafting block inventory, and put them into a furnace, for example.
