I used to make spaghetti for a two year old and it is the only thing that I have seen him eat willingly. He eats it like a fiend.
The mother wants to introduce more fibre in his diet but I am out of ideas because I suck donkey ass at cooking. I once tried oats-banana-cinnamon pancakes but the child spit it out because it tasted like shit. (I have posted about it before.)
If you have medium or high fibre recipe suggestions please share. It's a bit of an odd request so sorry about that but I don't know where to turn to. The internet is a search engine optimised wasteland.
I think you should consider adding food into the spaghetti.
If you can familiarise him with new flavours and new textures that are inside of his comfort zone then it's likely going to be less of an uphill battle than trying to get him to eat entirely different dishes.
First stop is switching to wholemeal pasta, since you are looking for fibre. I guess they call it whole wheat pasta there? If you slightly overcook it, the texture will be pretty close to pasta made with white flour so it shouldn't be offensive to the kid.
The next stop is to get some red lentils or some lentil flour and incorporate that into the sauce. This will add some fibre and it's nutritious.
Then try adding small bits of vegetables. Grate some carrot into the sauce when you're frying down the onions. Do the same with zucchini. Little bits of red capsicum should also be okay but too but you can mince it in a food chopper if you really need to hide it.
Then start getting creative. Add frozen spinach, finely chopped cores of broccoli and cauliflower, that sort of thing.
Was just about to say: finely chopped kale works really well in a red sauce, the dark green lacinato kale is better for fine chopping over the curly stuff
I grated some carrots into the sauce today and he really liked it. I grated it finely and boiled it for about 8 minutes. Then threw it in when I cook the pasta and sauce together and cooked for four more minutes. The carrot had turned into a mush with the sauce but he really liked it.
Great advice. Thanks.
