Puppy who eats anything will barely touch it

Bought the rice and lamb stew for my 1 year old as a treat but she did not like it. I put it out last night for 45 minutes and she didn't touch it, so thinking she just wasn't hungry I put the rest in the fridge and told my spouse to give it to her in the morning and nothing. She picked at it a little and then ignored it. She chose her kibble over this food
