STEP 1: Spread seafood in a glass or non-metallic container. Squeeze 8-10 of the limes, strain, and pour juice into the seafood to cover completely. Cover dish with plastic wrap and refrigerated at least 8 hours, or overnight.
STEP 2: Drain seafood to remove juice.
Place seafood in a mixing bowl. Toss all other ingredients with seafood,
adding salt and pepper to taste. Finish by squeezing juice of remaining
limes onto salad and serve.
