A small handful of flat-leaf parsley, roughly chopped
4 tablespoons natural yoghurt
Method
Soak four wooden skewers in water.
Soak the tuna chunks in lemon juice and harissa and let them marinate for 10 minutes.
In a pan, cook the grains as per packet instructions.
Then, add the cumin, spring onions, salt and pepper to the cooked grains and toss with 2-3 tbsp of lemon juice, depending on how bright you would prefer it.
Place the tuna chunks on four skewers.
Heat a grill pan until it's hot. Then, grill the skewers for one minute on each side.
Toss the vegetable and herbs along with the grains in a bowl.
Serving Suggestions: Serve the tuna skewers with seasoned cucumber and grains plus the yoghurt which has been mixed with some more harissa on the side.
