How to meal prep without a stove

I don’t have a stove at the moment but I have groceries that I already bought that I need to use to meal prep for the week or else they will go bad

I have an airfryer to make my chicken in but I don’t know how to make the orzo pasta

I have a crock pot but the orzo has to be cooked by itself for this recipe so it’s not going to take up a lot of room in the crock pot you know?

I’ll be cooking all but 2 servings of a bit of orzo so it’s enough to fill up a large pan but is that too little for a crock pot??
