Tuna steak with quinoa and caramelized vegetables

When I cook quinoa, I always cook the whole bag, and just keep it in the fridge for the coming days meals - EASY! I am also not a big planner when I go shopping, so I typically buy a random selection of vegetables, that I can easily transform into something delicious in no time. The vegetable recipe today, is actually a recipe from my cookbook Eat. Race. Win. which is my second cookbook, that I wrote with Dr. Stacy Sims. Check her out if you are a female athlete, she is really cool.

Alright let's get to it!

Tuna steak with quinoa and caramelized vegetables

Yield: 2 servings

Prep time: 10 min.

Cooking time: 15 min.


  • two tuna steaks (or other fish you have available)

  • 1 large onion, peeled and halved from root to the top

  • 1/2 cauliflower, cut into large florettes and then split lenghtwise.

  • 1/2 oxheart cabbage, sliced into

  • 150 g quinoa

  • 1 lemon

  • olive oil for cooking

  • 1/2 tsp. salt

Step 1.

Cook the quinoa in lightly salted water according to the package instructions.

Step 2.

Half the onions with the shell still on, follow the image instructions underneath ( you are welcome!).

Cutting the onions in half with the shell on makes them easier to peel - in my opinion.
