Oh my, this week. It’s been long! I’ve been waiting all week for weekend so I can actually have TIME with my husband. Ya’ll, he’s been away for 6 weeks. We need some date nights and a lot of catch up time. But guess what? Poor guy, all that work and travel caught up to him. He’s sick. So instead of going out, I plan on staying in and getting this man fed with good homecookin! I mean, the healthy “gonna kick this sickness to the curb” kind of meal.  But in all honesty, this sweet and tangy baked cod  is really just a super tasty nourishing meal in itself. A honey of a recipe. Except let’s swap out honey and use maple. Mmmm K? Maple mustard poppyseed baked Cod. Um, the sauce itself is TO DIE FOR. But pair that will light and flakey baked Cod (via sizzlefish) and you’re even more golden. Haha, see what i did there?

But before I dive into this golden goodness, I have a story to tell about this dish. . Besides the fact that it has a cute name. Yes, we know that. Maple Mustard Poppyseed  –> cutest baked COD name ever!

You see, this dish (or more specifically, this poppyseed sauce) would have never been allowed in this house had it been made over the past 7 years. I’ll give you $50 bucks now if you can tell me why. Anyone, Bueller? Bueller?

No guesses?

POPPYSEED! That, my friends, is death talk for any professional athlete or elite athlete. Poppyseed with RUIN drug tests. I know, so crazy, right? But it’s true and a few of my husband’s pro athletes friends have “accidentally” eaten poppy seed in a muffin or dressing and their test results have come back positive.

That being said, we avoided poppyseed like the plague. Until NOW! Hoooooray! The positive thing that comes from my husband’s pro athlete retirement. Haha, like eating poppy seed baked goods and making this amazing maple mustard poppyseed sauce. It’s the little things right?

Truth be told,  I really do love poppy seed dishes and missed it so much! Plus it’s like a tiny little “pop” seed of power minerals! Iodine, zinc, copper, manganese, and magnesium to name a few. Hmmm… come to think of it, that’s probably half the reason why I made this sauce combined with baked cod. Extra nourishment! Yes, the zinc and iron and calcium in poppy seeds will surely have the Kiwi back to health in no time! Zinc being a KEY factor in immunity and building new cells for the body. The nerdy nutrition side of me loves shines through!

The other half of my reason was just selfish desire because I really love love this maple mustard sauce on fish and chicken. Totally works, right?

    Ok… So I to substitute cod for salmon and chia seeds for poppyseeds because that’s what I had available. This was exactly what I was hoping for when I went searching for a maple mustard fish recipe. It was delicious!! Quick, savory and sweet. Complemented the fish perfectly! Can’t wait to try it with the salmon. Thank you for sharing. 🌺

      sure! you just might need more marinade to really make each piece of chicken flavorful. Does that make sense?
