The EU hasn't ruled that any compensation is due if you don't get your first choice of food. And it's not as if you had nothing whatsoever to eat anyway, plus the crew would have worked something out if you hadn't been able to eat at least something from the meal that you were given.

You've been given compensation that is way in excess of what BA would normally give you. The value of the Avios you've been given is probably somewhere around $100 (it's almost certainly in the $70-$140 bracket). It is beyond almost all of us to see how you think that you have not yet been properly compensated for what happened. Not getting your first choice of airline food is probably worth no more than a tenth of that.

If you are serially disappointed by the compensation offered by different airlines, then it may be your expectations that need to be reset.
