Super easy, super tasty, super healthy, super quick – what more could you want? You just have to remember to marinade the tuna ahead of time. If you don’t have teriyaki sauce, try marinating it in a little soy sauce, lemon/lime juice and a dash of salt and pepper.

Serves: 3-4 as a main course
Time to prepare/cook: 5 minutes to marinade the tuna ahead of time; approximately 15 minutes to prepare and cook the tuna and spinach
Ingredients
400-500g fresh tuna steaks (allow 150-200g per person), 1 to 2 cm thick
400-500g of washed spinach (1 large bag)
1 teaspoon crushed garlic, or 1 garlic cloves chopped finely
½ teaspoon of nutmeg
Teriyaki sauce to marinade the tuna
1 tablespoon sesame oil for frying the tuna – use olive oil if you don’t have sesame oil
1/2 tablespoon of olive oil to cook the spinach
Optional: Sesame seeds to coat the tuna in a light crust (looks good for any guests)
Lemon wedges to serve
Optional side dishes. Tzatziki or mango salsa (see other recipes)
Pots & pans needed: 2 large frying pans, chopping board
Method
Cover the tuna lightly in the teriyaki sauce and marinade for at least an hour before cooking in the fridge; if adding sesame seeds, put these in a bowl just before cooking and gently press the marinated tuna into the seeds until both sides are covered
Add the spinach to the pan with the olive oil, garlic and nutmeg and fry on a medium-high heat (6 on a scale of 1 to 9), stirring regularly so the spinach wilts through evenly – this should take approximately 5-10 minutes depending on the size of the spinach leaves (baby ones take less time to soften down)
At the same time, splash a little sesame oil into the other frying pan and warm it up to a high heat (7 on a scale of 1 to 9) for 2-3 minutes
Cook the tuna for 2 to 4 minutes on each side, depending on how rare you like your tuna – the tuna in the picture was cooked for about 3 minutes on each side
Once the tuna and spinach are cooked, leave the spinach in the pan to stay warm (heat off), while you quickly slice the tuna
Arrange the tuna slices on top of a bed of spinach on each plate and serve with lemon wedges, and optional side dishes, plus a little crusty bread
