haha!
Hmm... my next go to meal would be risotto, it is quite quick - my nephews like it quite simple, made with a fried onion, some garlic and then add rice, stock etc as normal and near the end add frozen peas and broad beans, top with cheese? It freezes well as long as you defrost slowly (i.e. don't do what I did last week and blast it in a pan in a rush or it will dissolve...)
This also works so well with finely diced leeks sweated in butter then add rice, dried thyme and stock, I top with toasted seeds or chestnuts. But less kid friendly ime.
or fritatta, if they like eggs, I use pre-boiled carrots, spuds, raw sliced pepper, tomato, pre-cooked broccoli, sliced onion and garlic, pour over beaten egg with a bit of milk in it and oven for 30-40 mins. I serve with salad.
OR we have a meal we call "crudites"
which is slices of ham, cheese, sticks of carrot, celery, pepper, radishes, cucumber, crackers or bread and hummus, olive tapenade all set out and people help themselves.
Takes 10 mins to put out. If there's a warm element e.g. saus rolls/quiche people totally think it's a real meal...
