Help me finish this recipe for greens

[laohaire]

I belong to a CSA and we are getting bushloads of greens I'm enjoying making them in different ways to keep things interesting. One time I sauteed senposai (Japanese hybrid between cabbage and mustard greens, very nice) with butter and coconut shavings. The coconut was unfortunately sweetened; I couldn't find unsweetened at the store. Anyway, the total effect was potentially intersting but way too sweet. Anyone have any ideas for balancing the sweet with another interesting flavor?

Maybe lemon juice? Any other ideas?

balsamic or red wine vinegar would probably work too - though I'm not sure I've used either of those with coconut.

lemon or lime juice though should be great!
