16 month old refusing food

She used to eat anything i put in front of her but now she wont eat anything i cook myself.

She only wants to eat bananas, goldfish, cherrios and microwaved vegetables.

Im not cooking anything crazy either. I made chicken, potatos, and carrots. She wouldnt touch it. She just cried.

She barely eats meat anymore. The other day i broke down and gave her mcdonalds nuggets because she actually ate them.

I know toddlers go through phases but honestly i hate making two dinners.

What can i do so she will eat again ?
