I also have pretty well stocked food cupboard with things like cereal, beans, jam, tea, coffee, table sauces, herbs and spices, condiments, flour etc.
We all have eggs and toast for breakfast most days.
Lunch is pasta salad for DP, free for dsd at school and I WFH so usually just have leftovers or something from the freezer.
Dinners are various, but often have a veg curry, stir-fry, roast dinner, pasta bake, pizza salad and wedges, wraps, spanish omelette.
