I see what you're getting at regarding subconscious free will. But the workings of the subconscious are determined by causes. The structure of the brain, the brain chemicals, memories of past experiences, expectations of future events. With the example of what to eat for breakfast, that decision will be determined by factors such as which you prefer the taste of, which you know will keep you going longer, or which you consider most healthy. Which ever way your subconscious leans in each of those regards, is determined by other factors.
