Dijon Horseradish Crusted White Fish

I know I've posted a hundred and ten tilapia recipes but it seems to be a staple for us because it's inexpensive and is so mild.   In a random moment of inspiration I googled horseradish tilapia and found a perfect match. 

I only altered a few things. 

I added some garlic and seasoning and increased the amount of horseradish and then divided the ingredients by 2 since we only had two fillets.
