Just to answer a couple of questions. What I buy is pretty much all fresh. I think I have bought about 10 ready meals in total since ds1 was born 4 years ago! I will, however, confess to usually having a box of either fishhfingers or chicken nuggets in the freezer for emergencies.
Our meals vary all the time depending on what I can get reduced, but we have meat casseroles & hm Curries, pasta with 5 veg sauce, meat (chops, steak, gammon) with potato & celeriac mash & veg, roasts, hm meat pies topped with mash, all kinds if fish (herring, mackerel, salmon, Coley, sea bass) with rice, game (usually as casserole or pie). Our fruit bowl usually has at least 3 kinds of fruit, plus dried & pureed fruit which I freeze (mixes well with porridge or rice pudding). Kids also have yoghurts & custard, plus the usual cakes & biscuits for snacks. Usually have some ham, cheese (different sorts, ds1 favours brie), eggs in fridge. So, not a bad diet, I didn't think 
As I said before, this is achieved by going shopping at inconvenient times & bagging bargains. Yesterday I got a family pack of pork chops for 80p,, family size steak pies for 70p, fruit salad pots for 10p each, a celeriac for 7p, pack of fresh doughnuts for 13p,, finest choc muffins 40p,, fresh cookies 20p (treats as had friends over).
It also helps that both dses are very unfussy & will eat anything. They have had to, as I refuse to believe that children should eat separate foods such as only ever nuggets, fishfingers, sausages, smiley faces, so I buy very little of this ,& they eat what we do.
Apologies for typos as on phone.
