His apptetite is miss up

Today I decided to fix some tocino and stir fry green beans (like the one we usually buy in karenderia in the philippines)for dinner. I thought hubby would love it. He usually love all the food I cook and I never heard him complaining about my cooking. But today I was a bit upset because his appetite is miss up again and he end up couldn't eat the food because his taste isn't right. I really wish that he will eat like he use to because I want him to gain some weight.
