Cereal (midweek) or pastry for breakfast.
Mid-morning piece of fruit.
Lunch can be anything - sandwiches, homemade sausage rolls, salads, soups, leftovers from the day before, once a week nuggets and vegetable sticks with dipping sauce, sometimes sushi. Seasonal fruit for pudding.
Dinner - again, anything goes. Yesterday it was aubergine moussaka, the day before chilli con carne, one day will be cesar salad, another meatballs and mash, tuna and pasta bake, pasta and breaded Polish sausages, homemade pizzas. Pudding, if it happens, is either fruit (sometimes with custard or cream), Angel delight or ice lolly.
To be honest, other than lunch, which can be more varied due to a lack of time/ food and space restrictions, it's pretty much the same as we'd have during term-time
