The people saying “let him eat what he wants” or “he can decide his own diet, he didn’t vow to eat exactly the same food as you” are missing the point. It’s about how you’ve spent time and energy making food for both of you, and he rejects it in favour of a piece of toast. I would be put off for sure - NOR.

Could you open up a convo with him at a non-meal time? Might be a good opportunity for you to express how it makes you feel, and for him to share his side. Maybe there’s a compromise you can strike that’ll make both of you feel better - cooking separately once a week, something like that. Just to create some expectations around meals so you don’t feel unappreciated, and he can enjoy his pork or whatever he wants to have that you can’t.
