he never eats my food?

my husband doesnt ever finish the food i make for him. hed only take a few bites and goes off to eat candies and chips. his plate always look like it hasnt been eaten, but played with. i get sooo annoyed by it sometimes, he always waste food. i dont even know what to cook for him anymore or what to even buy. ive talked to him about it and he just said for me to cook whatever and hed eat whatever i cook. lies. he used to eat them a lot, but not anymore. what should i do?
