2 tbsp chopped fresh oregano
2 tsp sesame seeds
1 tsp ground cumin
1/4 tsp crushed red pepper flakes
1-1/2 pounds skinless wild salmon fillet, cut into 1-inch pieces
2 lemons, very thinly sliced into rounds
olive oil cooking spray
1 tsp kosher salt
16 bamboo skewers soaked in water 1 hour
Heat the grill one medium heat and spray the grates with oil. Mix oregano, sesame seeds, cumin, and red pepper flakes in a small bowl to combine; set spice mixture aside.
Beginning and ending with salmon, thread salmon and folded lemon slices onto 8 pairs of parallel skewers to make 8 kebabs total. Spray the fish lightly with oil and season kosher salt and the reserved spice mixture.
Grill the fish, turning occasionally, until fish is opaque throughout, about 8 to 10 minutes total.
