I don't believe a healthy wholesome diet can be got with a microwave and few take-away menus... so I shall judge those I consider too lazy to learn to cook decent food for themselves.
Judge away. People - even judges - do make wrong judgements, you know.
The last takeaway I had was a pizza with friends in their garden last summer. Unless you call fish and chips at the beach on a day out, a takeaway too. I've had both of those last year - and I use my microwave a great deal.
A conventional oven and hob is
in no way necessary to have a healthy wholesome diet, and I have not had one for many years, unless I've been in rental property where such was part of the installations. In which case the oven has usually been used as extra storage.
If I were cooking 3 traditional meals a day for a sizeable family, no doubt I would 'miss' the ability to batch bake on a twice or thrice weekly basis, roast joints to serve half a dozen - with the spuds underneath and the yorkshires above - and have a selection of veggies, custard and a steamed pudding bubbling away on the hob, and a pan of chips too. Of course that is if you assume that the above-mentioned is a 'healthy wholesome diet'. I don't, personally.
The equipment in one's kitchen has very little to do with one's ability to prepare a healthy, wholesome diet, and it is perfectly possible to have a healthy, wholesome diet without what is thought of, in the UK at least, as a 'properly-equipped' kitchen with a full oven and hob.
Perhaps those who think that this is not so, have never lived in places where a kitchen is not routinely equipped as are those in the UK, but which nevertheless often manage to have a much healthier and more wholesome diet than many of those (supposedly) 'properly' equipped kitchens manage to provide for their users ...
