I am the caregiver to my mom (89). She will wake me up to tell me what her plans are for dinner. Any advice?

My mother woke me up to tell me that she will be making chicken... in addition to other items for my son and daughter-in-law. I said they won't be here til 10 pm. She said we'll eat it then I said I really don't know what I will eat at dinner. This happens everyday she will tell me at 9 am what she is making. I have told her for years not to be the decision maker for what I eat. It goes in one ear and out the other. She will make enough food for 20 people and then get mad or mumble under her breath when no one eats it. I can't take it. She doesn't listen to what you tell her and then gets mad. She is obsessed with meals and food. My kids were coming in from out of town so of course she woke me up at 10 am to tell me what she was gonna make. Again like 2,000 times I said can you stop. So I told her I didn't know what I was gonna eat for dinner. So she made so much food as always. I told her that the kids were coming at 10 pm. She said as always oh I thought they were coming in the afternoon. I don't know why you think that? So when she asked me to eat what she made I said no thanks then she mumbled crap under her breath because she is miserable. And said I'm not cooking. So I saw her make a doggy bag another thing she does all the time and she tells me to tell the kids about it. Okay again I will. When I went to pick them up and we returned here she comes to the garage at 10 pm I made dinner for you guys but I thought you were coming in the afternoon. ARE YOU KIDDING ME. My daughter was like oh my God with the food. Needless to say they stayed in a hotel. If we had eaten out she would have complained about no one eating. Well no one told you to cook. In the garage I told her I already told the kids. Then she goes on to say that she has it in plastic bags in the fridge. I said ok ma I told them so she mumbles and walks away. So you waited up to come downstairs at 10 pm to tell them about the food she even put their name on it. I'm going nuts. Eat eat eat... it's really good. It's moist it's so fresh. I don't care stop. 30 years of this is enough. What is the best way to deal with this. It's very wasteful and we are tired of it. I cook for myself. My kids are even tired of it. Enough. Don't get me wrong we love her and appreciate her but jeez let me be an adult already. Stop obsessing about food. At 89 she was probably just sitting there waiting . If it had been midnight she would have done the same thing. But oh no she doesn't have a problem. Yes she does it's toxic behavior and that's just one thing.
