Plant-based Tuna Steak


When we first saw the idea of vegan tuna especially out of watermelon, we honestly thought it was ridiculous and that this would never be worth the effort however we were wrong! This is delicious and so worth trying. It makes a fabulous centrepiece dish and although it takes a long time, the oven does all the work!

Takes 2 hours 40 minutes

Serves 500

Ingredients
 

  • 1 baby watermelon

Dressing:

  • 1 tbsp sesame oil
  • 1 clove garlic
  • 3 cm cube piece of ginger approx 8g
  • 2 tbsp tamari/ soy sauce
  • 1 tbsp maple syrup
  • 1 tsp mirin or vinegar of choice
  • 1 tbsp black sesame seeds
  • 1 tbsp white sesame seeds

Instructions
 

  • Preheat the oven to 190 degrees C
  • Using a small knife carefully remove the skin of the baby watermelon.
  • Add to a baking tray and bake for 2 hours turning the melon every 30 mins so that it cooked evenly.
  • After 2 hours it will have developed a light skin and started to lightly brown around the edges, time to make your dressing.
  • Peel and finely grate the ginger and garlic, add in the rest of the ingredient for the dressing and mix well.
  • Remove the baked watermelon from the oven and using a pastry brush, brush all the exposed watermelon in a generous coating and baking for 10 mins.
