Cam's mom, in terms of veggies. Mine loves fried mushrooms (either dry fried or in a little butter), asparagus, green beans, aubergine, courgette, peas, sweetcorn, roasted onion. He also went off sweet pot and carrot for a while I think he just got bored of it, or maybe he realised he didn't 'need' so much of it (they firm up his poo and it can get too firm if he eats too much of those).
For lazy meals I used to throw some frozen veg in with pasta whilst it was cooking then after draining stir in some pesto or tom puree and cheese or a spoon of cream cheese to melt, and some times a can of fish (tuna or mackerel). It makes for a really quick and easy meal but still balanced.
I've let DS drink the fruit juice on the rare occasion I've given him frozen fruit. When it is defrosted it is pretty squishy and there's lots of juice. I let him drink it straight form the bowl immediately after finishing the serving of fruit. I think/hope this way he will not associate it with being a 'drink' but instead part of the fruit serving and it isn't an additional acid attack on his teeth. I too wouldn't introduce any drinks other than water/milk, I worry too much about his teeth.
I made chicken meatballs the other day, but with chicken breast whizzed up (rather than bought mince) and mixed with breadcrumbs and a little low sodium seasoning, then rolled and fried. I was surprised how much I enjoyed them - like getting a hit of junk food but it not being junk. I'm not even keen on junk food but sometimes just get the urge for something processed and reconstituted - how odd! - these fulfilled the craving and DS loved them too.
