Having a will is what I think we agree on. How freely that will can be exercised is open to question. If one's will is, indeed, free, but one is constrained from exercising it entirely, then it is really useless to consider it to be free. It would be like saying that a person who is enslaved for life to another person has the freedom to do anything he desires.
Free will at its core is just the ability to form thoughts and make decisions, being conscious of your existence and circumstances and able to have an opinion and make decisions based on it, consciously, not just obeying instincts/drives.
Having a natural/instinctive drive to eat, you eat, but having a will, will be able to make other decisions. You may decide you're not that hungry and skip eating, such as dieting or fasting, or maybe you plan to do an activity where eating right before it is a bad idea, like swimming. You also make a decision on
what to eat, or at the bare minimum, what you would
like to eat, if you do not have the circumstances to eat what you wish.
Being in circumstances where you can't have what you want doesn't mean your will isn't free.
Being in circumstances where there will be penalty for doing what you want doesn't mean your will isn't free. You still formed the idea and decision independently.
Therefore a free will
Free will person gets offered fruit, and thinks internally "I'd prefer a steak", they may still take the fruit and eat it, but they have thoughts regarding it.
No free will doesn't even think about it, and just eats the fruit offered, because of the natural drive to eat. They don't even have thoughts about what they'd rather have, or whether they should eat it or not.
Just natural drive, hunger, offered food, eat.
