Hi Carol, thanks very much for the question. Having a good store cupboard really makes improvising meals from the ingredients you're presented with so much easier.
Here's my list
Dried goods: pasta, rice, pulses, grains (a pressure cooker very handy to quickly cook the pulses)
Tins: tomatoes, anchovies
Various flavours/types of oil and vinegar
Bacon, guanciale, pancetta, parmesan
Herbs or green veg preserved in oil such as persillade (recipe in book), pesto etc
Strattu (very concentrated passata preserved in oil)
A well stocked dried herb and spice drawer
All purpose, strong white, rye, spelt flours.
Sugar
Fermented chillies, green veg etc
Frozen peas
I'm sure to have missed something
