Asperger's and Odd Eating Habits

I have highly unusual eating habits. I have  consumed the exact same  breakfast, peanut butter toast, every morning for five years. I love the absence of stress or thought involved in figuring out what to eat in the morning.
  Lunch and dinner are a different, more sordid story. Finding words to accurately state my mealtime dilemma doesn't come easily....but I'll try.
I cannot just eat anything. I have to ingest what...the inner chef wants and desires. If I have something that is not what "the inner chef" wants, I feel hungry even after eating a plateful of food. As an example, for the past three months I ate bologna/ pickle spread, once or twice a day. I'm a small serving, frequent meal kinda girl. If I ran out of bpickle spread and substituted last night's leftover chicken that I cooked for my son, even if it was a large portion, I would continue to be hungry until I went to the grocery store and made more spread.
For those three months, I made bp spread and pasta with sauce every few days. Combined with my habitual breakfast that was 90% of what I consumed, every day for three months.
It's a good news, bad news habit to have. The good, nay, the great news is the only thought given to mealtime was, do I have all my items? Do I need to go to the store or just cook up some pasta or grind up bologna? Mealtime was predictable, simple, easy and relatively stress free.
The bad news? Argh, the deeply unpleasant feeling where the "inner chef" wants to change the menu...and nothing works...I cannot find the correct food for the chef. I try this or that but nothing sounds or tastes good. The chronic, gnawing hunger refuses to abate. I feel empty, unfulfilled...nothing is right. I'm continually starving until I find the "correct" food for inner chef. I try eating this, that, the other thing but I'm still starving, no matter what or how much I eat.
My steady diet was at least three months. I think that was a record and I could see it coming down the pike, rolling down the hill, like an avalanche that I knew would bury me alive.
I wish I were joking, or at least capable of exaggeration but, honestly, it sincerely is a miserable experience between appropriate meals. Think constant hunger for a solid week. Seriously, it's non-stop. I am quite grouchy, off balance, insatiable and starving. My only hope is that my belly, brain and inner chef find a menu item that will work, and soon. I grow fat, despondent and more miserable with each passing day.
  I doubt few can comprehend my dilemma. I wish it were a joke or that I knew of one other person that experiences this.
This is not a favored event for me...this starving in-between time. I have no idea when it will end. What is it my body requires to feel full? The formula changes every few weeks or months.....
