What are the ingredients of your marinade...Might be easier to pair a salad if we know wots init?
A spicy pineapple salsa comes to mind, but might clash. Something with coconut??
Just had a peek at my Levi roots book for you... To go with a lime, angustura and marmalade marinade, he reccommends a pineapple,avocado,orange and mint salad with a ginger dressing.
Recipe for dressing :- Juice of 1 lime, S&P, 2 tbs olive oil, 1/2 knob stem ginger chopped fine, 1 tbs ginger syrup
...Sounds great?
