I like an omelette with some bits of veg (mushrooms, courgette etc) and grated cheese in for a quick, hot lunch.
Hippa, I think that's the way I'm going with my ds too. Generally he has eggs (fried or scrambled) on wholemeal toast for breakfast, with extra bacon, sausage, mushroom and tomato at weekends. Weekdays he has school lunch (2 courses, but small portions and the quality is good, no processed crap), and weekends he has what I have (a salad, omelette etc) but with a bread roll/pita bread as well.
He usually has one snack a day when he gets in from school (we don't usually eat dinner until about 7.30) which will be a piece of fruit (apple or a few strawberries) and/or a home-made biscuit. And no, I don't eat my own home-made biscuits!
Dinner, he has what I have but with an added carb e.g. if I have bolognaise and buttered veg, he has that but with pasta, if I have salmon in garlic cream sauce and veg, he has that with boiled potatoes etc. Drinks, he has one apple juice a day (with dinner) and drinks water the rest of the time.
He doesn't like fizzy drinks, and I don't buy any other snacks except the aforementioned fruit and biscuits. Sweets he only gets if someone has given them (e.g. Christmas, Easter, or recently when a friend gave me a box of fudge as a thank you for something I had lent her).
I guess that's not too bad. He knows I use real fats (butter and olive oil) and is happy with that. Fortunately he likes most veg and salad, and is happy to eat things like pork crackling.
