DS1+2 (especially Ds2 though) love spaghetti bolognese but wouldn't touch meat, mushrooms, onions, courgettes, tomatos, all the ingredients basically with a barge pole.
When they see it cooked they ask if it's for them and I always say "No, you've just got the sauce"
The sauce is ALL the ingredients just blended down to mush. They eat tonnes of it, it's probably the only dinner I can guarantee they will eat.
