Spicy Paleo Fish Cakes

It’s no secret that tinned tuna is a super ingredient: it’s affordable, convenient and packed with protein. But if you’re anything like me, one bite of tuna salad and I’m sick of it. I wanted to find another way to eat it that was still easy and healthy and these delicious spicy paleo fish cakes are just that. Give them a try, you won’t regret it. They have a great balance of zesty lemon, spice, and a hint of sweetness from the sweet potato. Yum!

You can tailor the level of spiciness to your liking by adjusting the cayenne pepper and adding or leaving out chilli or jalepeno.

These are also great if you’re a food prepper because they store in a sealed tupperware in the fridge for about a week.
