I'm on the fence on this. I feed my DC1 the healthiest diet possible within the confines of what they will eat. Realistically, that also involves a lot of "cheaper" food that I wouldn't necessarily enjoy eating myself - cereal in bulk, toast and spread, plain cheddar, fish fingers, those 50p supermarket pizzas (DC loves them as they get a "whole pizza" to themselves), supermarket bread, own brand fries etc. I do add 2-3 portions of veg to the side of every meal, but again it's cheaper veggies like carrots, peas, sweetcorn because that is what DC1 eats. I am constantly concerned about DC1's protein intake so pile on the milk, peanut butter and eggy pancakes.
DC2 is much younger and hasn't reached the fussy stage yet so gets a wider, better-quality range of foods - nice stews, seafood risotto, omelettes, steak mashed down, spinach, asparagus, green beans, tomatoes, peppers, nice cheese. Essentially a mixture of what DC1 is having and what I'm having.
It is always open to DC1 to try the foods which I am eating, as I remind them regularly. I also spend a fortune on fresh salmon, trout and strawberries out of season, as these are things that DC1 will actually eat.
But yes, if you joined us for dinner on an average evening, I'm afraid DC1 would look very much like the "poor relation" in terms of what was on their plate. And I can sympathise with just giving up to avoid waste and throwing food away, though I wouldn't do it myself.
