I have always tried to introduce my son to many different flavors and foods. He has eaten, aside from portuguese food and all-american food, japanese food, indian, chinese, korean, mexican and many other foods that we want to make sure at least he tries. But he's a simple guy and would be happy eating just bread and drinking milk.
For the past year he has been into phases and for months all he wanted to eat was "white rice with meat". And for more that I tried to vary the types of meat or how I cooked the rice, it pretty much had to fit within his description or it was a constant fight for him to eat at all (have I ever mentioned he's a picky eater?).
The current phase we're on is the "pasta that I like" category. That means a pasta made with a white sauce. However I make the sauce it doesn't matter, with cheese or not is indifferent, as long as it's white and creamy. And whatever goes with the pasta can be or not or his approval. His very favorite, though, is scrambled egg and ham with his white pasta.
