Cook your grain base: Rinse the quinoa or farro.
Cook according to package directions with a pinch of salt. Fluff and set aside. For extra flavor, stir in a squeeze of lemon and a drizzle of olive oil.
Preheat the oven: Heat to 400°F (200°C).
Line a baking sheet with parchment for easy cleanup.
Season the salmon: Pat the salmon dry. Rub with olive oil, salt, pepper, smoked paprika, oregano, lemon zest, and minced garlic. Place on the prepared sheet, skin-side down if using skin-on.
Roast the salmon: Bake 10–14 minutes, depending on thickness, until it flakes easily and is just opaque in the center.
For crisply caramelized edges, broil for the last 1–2 minutes. Squeeze half a lemon over the salmon after baking.
Make the sauce: In a small bowl, mix Greek yogurt, tahini, lemon juice and zest, grated garlic, olive oil, salt, and pepper. Whisk in water, 1 teaspoon at a time, until it’s drizzleable.
Toss the veggies: In a bowl, combine tomatoes, cucumber, red onion, olives, and herbs.
Add a pinch of salt, a splash of olive oil, and a little lemon juice. Fold in feta, if using.
Build the bowls: Spoon warm grains into bowls. Add a generous portion of the roasted salmon, flaked into large pieces.
Pile on the veggie mix. Drizzle with the lemon-tahini yogurt sauce.
Finish and serve: Add any extras—avocado slices, greens, or pine nuts. Serve with the remaining lemon half for extra brightness.
