My son loves pasta with roasted vegetable sauce - all we do is chop onions, peppers courgettes garlic, carrots, shove it all in a roasting tray and blast it in the oven at 200C for 30 minutes. When it comes out we mix with a couple of tins of organic chopped toms, blitz it in the mixer,and freeze what we don't need immediately.
As for finger food, son always enjoyed a handful of cooked broccoli or mixed veg as a starter to his meals - this meant he could mess around trying to eat the veg whilst we got his main course finsihed and could then feed him in between handfuls of the veggies. I found that frozen organic vegetables were the easiest for this!
Also - don't be afraid of stronger flavours - my son devours garlic bread (not that healthy I know), but also sardines on toast even (mild) curry. Just be adventurous and, if its refused first time round try it again in a week or two.
By the way am I the only dad on the site?
