Good Grief all these comments on being 'lazy! What about people with mobility issues in their hands? It can be very difficult to shell eggs, grate cheese and chop vegetables when you have,say, severe arthritus or even an apurtation of one limb!
I would not buy shelled eggs as we have hens, apart from that I do buy grated cheese ,as well as normal cheese, frozen chopped onions (so convenient), frozen chopped mixed peppers (no waste if you only need half a cup), and many other frozen ready prepared veg,along with fresh when in season. Frozen or packet mash in the summer, as the new potatoes do not mash well.
This 'Lazy' cook makes everything from scratch but certainly would not get sniffy about ready meals either.
