One of the recipes I've made lately that Brandon and I LOVED was a Macadamia nut crusted halibut with mango salsa and coconut rice. It was UH-MAZE-ing!! Amazing. The best part? It was super simple and yet seemed so fancy/gourmet.
I searched the internet for a while to find the "right" recipe. Most of them combined the macadamia nuts with panko or other types of breadcrumbs/extras (which I had before and didn't like as much). For this dish, the simpler the better! :) Here's the recipe: http://homecooking.about.com/od/seafoodrecipes/r/blsea103.htm
Few tips....you absolutely need a food processer/chopper for this. I tried making it by hand chopping the nuts and it didn't coat the fish as evenly. This time I ran the macadamia nuts through a processer and it made a HUGE difference. Also, every oven is different so check on it periodically to make sure it isn't over cooked, this dish is so amazing because it's crispy on the outside and juicy on the inside!
For the mango salsa I just chopped up mango, red pepper, onion (purple), cilantro and a little chilli pepper, and squeezed lemon and lime juice over it. Try to refrigerate it for a while so it's extra cold. Yum.
