Minestrone is a great soup, I mainly use frozen veg for it, as I tend to use the rest ones for 'nicer' meals!
Tinned toms, Tom puree, garlic, mixed herbs, frozen veg, bacon from a pack of cooking bacon, a tin of beans, or lentils and some value snapped spaghetti, a bit of grated cheese, or cheese on toast with it.
I do similar with value noodles, garlic, ginger, mixed frozen veg, cooking bacon again, soya sauce and a fried egg on top.
The jars of garlic/ginger etc works out cheaper and keep for ages.
