What happens must happen, if salad must be ordered (determinism), steak is not a possibility. Steak or anything other than salad not being a possible selection, thus impossible, there are no alternatives in that moment in time, salad it must be.
And salad it WILL be. However, the steak is still a possibility that I seriously considered. In order to be seriously considered, it must be a real possibility. The steak was never impossible. It was a realizable alternative, just like every other item on the restaurant menu.
The steak met every requirement of a real possibility as defined in the OED (highlights mine):
possibility, n.
1. a. The fact of something (expressed or implied) being possible to one, whether through circumstance or power; capacity, capability, power, ability; (also) pecuniary ability, means. Occasionally in plural. Obsolete (in later use merged in sense 2a).
2. a. The condition or quality of being possible; capability of existing, happening, or being done (in general, or under particular conditions). Also: contingency, likelihood, chance.
Ordering the steak was a real possibility. It never became an actuality, but it could have been realized under different circumstances. The steak was never an impossibility.
Because it must be salad and there are no alternatives in that instance in time and place (the given conditions of determinism)...
There was a literal menu of alternatives. Any item on the menu "could" be chosen, even though only one of them "would" be chosen. That is what those words actually mean. And they must mean what they do mean in order for us to make logical sense of the real world.
... salad is entailed, not chosen. That which is inevitable is not a choice.
Choosing was deterministically entailed. There was no other way for events to unfold. An inevitable choice is still a choice, and it is still the result of an inevitable choosing.
Determinism, in philosophy and science, the thesis that all events in the universe, including human decisions and actions, are causally inevitable. Determinism entails that, in a situation in which a person makes a certain decision or performs a certain action, it is impossible that he or she could have made any other decision or performed any other action. In other words, it is never true that people could have decided or acted otherwise than they actually did.''
Britannica is only correct in the first sentence. Determinism in philosophy and science, is the thesis that all events in the universe, including human decisions and actions, are causally inevitable. This is a supportable thesis.
The notions that determinism can eliminate the notions of possibilities and things that "can" happen, even if they do not happen, creates a paradox that falsifies the claims in the second and third sentences. I've demonstrated this repeatedly. But, what the heck, one more time:
Waiter: "What will you have for dinner tonight?"
Diner: "I don't know. What are my possibilities?"
Waiter: "Because the universe is deterministic, there is only one possibility, only one thing that you can order".
Diner: "Oh! Then what is that one thing that I can order?"
Waiter: "I can't tell you until after you've made your choice."
A paradox is created by insisting upon only one possibility. There must be at least two real possibilities before choosing can begin. And, if it will be deterministically inevitable that choosing will happen, then it will also be deterministically inevitable that there will be at least two real possibilities at its beginning.
If you wish to solve the paradox or prove it does not exist, then please proceed.
Again: If something has not been determined to happen at a specific time and place, it cannot happen in that specific time and place regardless of such an event happening at a different time and place.
That's the point.
That's how determinism is defined. No alternatives in any given instance in time regardless of "what 'can' happen."

Britannica is correct in what it says about determinism, just as you yourself define it.
''Determinism means that events will proceed naturally (as if "fixed as a matter of natural law") and reliably ("without deviation") - Marvin Edwards.
''Fixed as a matter of natural law'' and ''without deviation'' is equivalent to - ''Determinism entails that, in a situation in which a person makes a certain decision or performs a certain action, it is impossible that he or she could have made any other decision or performed any other action. In other words, it is never true that people could have decided or acted otherwise than they actually did.''
There is no way around this. 'Fixed' and 'without deviation' negates choice....and we have the no choice principle of determinism.
This principle, as you can see, is entailed in your definition of determinism.
