I often make quick meals. As long as they are reasonably healthy and filling, no one would complain. DH certainly wouldn't say after the event that giving the dcs beans on toast wasn't sufficient. The dcs wouldn't complain, we are fortunate that they are not particularly fussy.
I do agree with what someone else said about it being in the mind and the issue partly being there is no meat.
We have quick meals (at least 2-3 days per week) for many reasons. Price is one, both of the electricity/gas if not using the oven and the raw ingredients. Also speed/convenience. Less preparation, less washing up etc.
Quick things we have include pasta with a fairly instant sauce. Either pesto or a decent jar brand, or cheese sauce (I make a large quantity and freeze it) Serve with fresh or frozen veg, e.g. peas or broccoli.
Beans on toast, or beans with jacket potatoes. Or jacket potato with other fillings.
"quick" risotto. Can't post recipes I literally make it up each time, any veg that needs eating, and bits of cooked meat hanging round, few prawns out of the freezer etc
Other days I do much more elaborate meals, home made chilli, home made fish pie from scratch, lovely roast dinners.
