Cut the salmon fillets into 2.5cm cubes. In a medium bowl mix together the oregano, olive oil, salt, pepper, garlic, chilli flakes, and sesame seeds. Add the salmon, toss to combine, and set aside to marinate for 15 minutes.
Prepare the barbecue for direct cooking over medium heat (180°C to 230°C).
Thread the salmon, asparagus, and lemon slices alternately onto skewers, and then grill over direct medium heat, with the lid closed, for 3 to 4 minutes. Using a metal spatula, carefully flip the skewers and grill for a further 3 to 4 minutes, or until cooked to your liking.
