I would have to agree with Elizabeth, I don't think there is anything worse than ordering a pie and getting heated up filling with a dry pastry top stuck on. Is there anyway that you can make the pies but just cook them to order? I can understand not always easy in that kind of environment but nothing beats freshly cooked food!
Some ideas for you, if I may....
Homemade soups such as pae and ham, roast pumpkin, lentil and pancetta, roast tomato and oregano, potato bacon and leek, chunky minestrone, french onion
Bubble and squeak with the added twist of chorizo instead of bacon and leeks, searched with grilled/roasted tomotoes or poached egg.
Stew and dumplings - stew made with lamb in a Morrocan style or rabbit stew with thyme, or use a cobbler topping instead
A vegetable crumble using roasted veg and tomatoes and cheese in the crumble mix.
Roast spatchcocked chicken (or chicken breasts) with lemon, garlic and olives.
Yorkshire pudding with different sausages or add mustard, herbs or onion to the batter
Shepherd's or cottage pie - add flavourings to the mash or make with italian style meat sauce
Pork chops with an apple and sage topping.
Roast vegetable frittata.
Fillet steaks with soft polenta and blue cheese
Lemon and parsley fried fish fillet
Pork fillet with apples and cider, sauce or pork chops braised with apple, leeks and bacon.
Homemade ice creams - summer berries, pear and cinnamon, banana and honey with nuts,
Chocolate fondant puddings with mascarpone or a good ice cream.
Chocolate brownie with coffee ice cream or sauce.
Strudels, tarts, rise puddings - all can have different additions and flavourings - can also do savoury strudels and tarts with onion, spinach and feta, cheeses, potato/rosemary/goat's cheese
Toffee apple pudding, sticky maple pudding with dates and nuts, bread and butter pudding with apricots and brandy or using croissants or brioche instead of bread.
Looks like I've been thiking too much!! Sorry for the long list. Helen
