Cajun Halibut with Fennel and White Beans

I made this a while ago, I THINK it was halibut, but I kinda forget. But you can make this with any firm white fish, tilapia, sea bass, cod, halibut. I normally just grab what looks the best for the money I'm willing to spend that day. The veggie mixture the fit is sitting on it one of my FAVORITE things EVER! Delish. Enjoy!

Ingredients (for 2):
2 servings of firm white fish
Cajun Seasoning
1 small yellow onion
1 large fennel bulb
1/2 can of white beans, rinsed and drained
1 cup white wine
1/2 cup chopped kalamata olives
2 cloves garlic, sliced thin
1 large tomato diced
handful chopped parsley
olive oil, salt and pepper
canola oil for the fish

Directions:
In a sauté pan, soften the onion, fennel, and garlic in some olive oil, salt and pepper. Once they become a little soft, add the white wine, olives and beans and simmer until the liquid reduces and creates a semi-thicker sauce.  Add the tomatoes at the end so that they still exist when you eat it.. Otherwise they will probably just disintegrate (unless you want that, which probably is cool too). Add some parsely and turn off the heat.
For the fish, just add liberally amounts of black pepper and cajun seasoning to both sides (the one I used was the Trader Joe's brand because my cousin gave me some to try, but they all taste pretty much the same to me). Heat up some canola oil in a pan and brown the fish on each side on medium heat. Depending on the fish and thickness the times will vary. For the halibut it was about 5 minutes on each side.
Serve the fish over the fennel mixture. I highly suggest drinking the rest of that white wine with this meal.
