Lazy: Frozen Pizza- always a couple in the freezer for emergencies although we do also make them, pesto and an extra jar of pasta sauce although we try to make sauce, packet couscous, stock pots/cubes, bread crumbs, pre batoned carrots (I only like them batoned and hate chopping them although I do spiralise 2-3 at a go and freeze portions) chips, mini frozen pastries for Sunday breakfast and always a garlic flatbread in the freezer.

I buy whatever brand loo roll is on offer. Kelloggs Cinnamon cereal on occasion- can't find a cheap equivalent.
