If using bamboo skewers, pre-soak for 30-60 minutes. You will need 10-16 skewers.
For oven: preheat broiler on High. For grill: preheat grill on medium high heat and oil the grates
Mix oregano, sesame seeds, red pepper flakes and cumin in a small cup or bowl and set aside.
2 Tablespoons oregano, chopped, 2 teaspoons sesame seeds, ¼ teaspoon red pepper flakes, 1 teaspoon cumin
For each kabob, take 2 skewers and thread a salmon cube with both skewers in a parallel pattern. Add a lemon slice and repeat with salmon and lemon to fill the skewers. You will end up with 4 - 8 kabobs total, depending upon the size and thickness of the salmon pieces.
1 - 1½ pound salmon fillet, 1 lemon
Brush the kabobs lightly with olive oil, season with a little salt and then sprinkle half the spice mixture on top. Turn the kabobs over and repeat with the remaining spices.
1 teaspoon salt
For the oven place kabobs on a flat baking sheet, then place the sheet in the oven about 5-6 inches under the broiler. For the grill, place directly on the grill grates. Cook 3-5 minutes each side, until salmon is cooked through and opaque throughout.
