Pan-Seared Tilapia with Chile Lime Butter

Why I Love This Recipe
I'm not sure where I got this recipe, but it's definately one of my weeknight faves!
Note: I like to double or sometimes triple the butter recipe, roll it into a log and freeze it for the next time I feel like making this fish - when ready to use it just cut a chunk off, stick the rest back in the freezer and you're good to go!
