Mediterranean Halibut Sandwiches

I've made this recipe twice now. I add the juice from half a lemon on top of the recipe's lemon zest, extra capers and salt to taste. This last time, I used a homemade challah bun...not the same as the ciabatta bread. My own preference, but the garlic-rubbed, toasted ciabatta bread really makes this recipe. Halibut is a great but expensive fish. Use cod or any inexpensive white fish. It is flaked fish in mayo, after all, so the value of the halibut is lost...just my opinion. I used cod the first time and Mahi-mahi the last time. Both tasted great. I will be doing this one again and again. Great recipe.

Great sandwich! I will use a lighter bread next time. Ciabatta over powers the lightness of the fish.
