Hi rooster,
My son refuse to eat my lunch today-fried tang hoon. Actually, I think it taste weird too. So I guess I will just have to make a better dinner for him too.
My son have food swings too, one day he likes cod fish, he can refuse to eat it the next day. But so far, his favourites are egg and carrots.
For vegetable soup, I just throw in carrots,onions, potatoes,pork ribs/ikan bilis to boil. You can put cabbage too. Sometimes you can add corn for sweetness too.
If your son likes soup, you can also boil chicken soup or fish soup.
Since your son likes eggs, you can beaten eggs to cooked vegetables and cook them like Frittata. You can check out the recipe at bettycrocker.com.
Don't worry, just try various ways to cook. Australia should have lots of ingredients for you to play with, I can't even find pork in Pakistan.
