Preheat oven 375 degrees.Note: Use the convection/roast setting if your oven has this feature. In a small bowl, combine tahini paste, olive oil, lemon juice, oregano, shallots, cumin, fennel, paprika, black pepper and salt. Mix thoroughly.
In a medium bowl, add the quartered tomatoes, chickpeas and lemon slices. Season with 1 to 2 teaspoons of the marinade.
Season the salmon with the remaining marinade.
Place two 1 1/2 quart oven proof baking dishes on a half sheetpan. Add 1 piece of salmon to each dish and pour/sprinkle any remaining marinade onto the fish.
Divide the tomatoes/chickpeas into two. Add it to each dish - sourrounding the fish with tomatoes in a single layer.
Bake for 20 to 25 minutes. The fish will be moist and tender and flakes easily.
Serve in the baking dishes or gently transfer to a plate.
Enjoy! Happy Cooking.
