Tonight we had a bean chilli for tea and normally Joseph would get some but my hand slipped and I put into much chilli powder for him

anyway asked him what he wanted and he asked if he could have a pizza, which I made him and then he PICKED

aarrrggghhh why ask for something if you don't want it (if he had had the chilli and not eaten it because it was hot I would have been fine).
Anyway he is sat here saying
"i'm hungry" well big bad Mummy has said as he didn't eat his tea he can go to bed hungry- now he is crying and saying his tummy is hungry
I feel at nearly 4 he shouldn't get his own way about this and because he asked for the pizza and didn't eat it he shouldn't get anything else.
Am I being cruel???
