How To Prepare Plant-Based Flaky Fish with Red Onion and Caper Relish


1. Make the Relish


Combine all relish ingredients in a bowl and mix to combine. Place in the fridge and let sit for a few minutes, so the flavors develop.
 

2. Cook the Plant-Based Fish Filet 


Heat oil in a non-stick pan over medium heat. Season the Kinda Cod filets with cracked black pepper and place them in the pan. Cook for 3-4 minutes on each side, until golden brown and crispy. 


3. Assemble 


Place cooked vegan fish filets on a plate and spoon over the relish. Serve with your favorite carb or a hearty salad. 


Tips & Tricks

  • Give It Time. Let relish sit for a few minutes, or even overnight, to develop deeper flavor. 

  • Use a Mandoline. To achieve extra-thin slices of onion, use a mandoline slicer.

  • Add Brightness. Squeeze a bit of lemon juice over the vegan fish before serving. 


  • Switch Things Up. Use fresh coriander, mint, dill, or oregano for a different flavor profile.
