Fussy eater

My son is 2.5years old. He used to eat most things except pasta and pizza.

He would have basically anything we were having. So over the last two weeks he has developed a thing of not eating a lot. Basically he will only eat processed foods which we used to give when we were short on time or we were eating said pasta or pizza and used to give him a small amount to try him (always refused).

So is it a phase?

I made him his used to be favourite yesterday which is a fruity curry with rice and peas, kept pushing it away. I made him a cottage pie, pushed it away.

He is non verbal still.
