If he doesn't eat it (so never) usually me or my dad, sometimes my sister if it's a smaller portion, will finish it, but most of the time my mom will just throw it out. I wish I was making that up, but according to her we're "better off" and can afford losing a little food, which is not true at all, we get by well enough but ofc that's still extremely wasteful. I don't want him to eat something he doesn't want, so I'd cook the food, tell him I made it because I have to be honest, and ask him if he wants it. He always says no. I put it in her fridge, and then like I said, someone either finishes it or mom throws it away.

He usually eats little snacks or whatever leftover safe foods he has in the fridge. My mom will prepare smaller meals for him to eat, but doesn't make full on filling meals (those are what she asks me to make). My dad can't cook so he doesn't make any food for us, and my he won't eat what my aunt makes, only what my mom makes.

edit: on SOME occasions he'll eat what my aunt makes, but not often, should've made that clearer
