If you look in the healthy extras sub forum, there is a thread in there for exactly what you asked, people listing what they are having as their healthy extras for today x
As long as the b choices aren't meat or carbs (which none of them are on that thread) then they all count for ee too. If you are a member on the official website you can select which day and if you are looking for a or b choice and it has every item that can be used on there x
