It sounds like both you and your mom need to work on how you communicate with each other.
If you wanted the meal, not just the sandwich you probably should have confirmed that was understood before having your mom place the order. Further, when the order was being placed you had a chance to say something, at least if you were paying attention and noticed that a misunderstanding was in progress.
Also, if there's a recent issue you're upset about, dredging up a bunch of unrelated previous disappointments to also be angry about is a bit unfair. Even if those previous disappointments are part of a broader pattern, it's often better to discuss how it's an ongoing pattern when you're not worked up over the most recent addition to the list.
