I am afraid that I am similarly "lazy".
If I was lucky enough to have a DS who could eat eggs, dairy etc., no doubt I would be rustling up omelettes and glasses of wine (presumably not for the DC though), but actually to have a meal that doesn't require any thought at all is a godsend (or washing up, more importantly).
At the moment (also very pg., ailments etc) I push on through until I can next justify giving fish fingers, oven chips and possibly peas.... at the moment I'm averaging every 7-10 days.
As for "a bit of salad". To me, preparing salad is not somethign I would be prepared to do for anyone if I was tired, so certainly not for small child who would need pinning down to eat it.
Good thing about this thread is that it will give some a chance to feel they are doing so well in making sure their child always had great food. Having a brother who lived on turkey burgers, chips and beans for approx. 6 years, and appears to be the brightest person I know, I'm happy with my efforts.
I also like the idea that the amount of tomato sauce DS likes to consume with it is consider an excellent source of lycopene, and you can't get much better in the antioxidant stakes.
