Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 425 degrees. Wash and dry produce.

Zest and quarter lemon. Halve, peel, and cut onion into ½-inch-thick wedges; mince a few wedges until you have 2 TBSP (4 TBSP for 4). Peel and mince or grate garlic. Roughly chop pistachios. Halve tomatoes lengthwise. Drain and rinse chickpeas; pat very dry with paper towels. Roughly chop parsley and chives.

In a small bowl, combine raisins with juice from one lemon wedge (two wedges for 4).

Heat a drizzle of oil in a small pot over medium-high heat. Add minced onion, garlic, half the pistachios (save the rest for serving), half the Turkish Spice Blend (you’ll use the rest in the next step), and a pinch of salt. Cook, stirring, 1 minute.

Stir in rice, ¾ cup water (1½ cups for 4 servings), stock concentrate, and a big pinch of salt. Bring to a boil, then cover and reduce to a low simmer. Cook until rice is tender, 15-18 minutes.

Keep covered off heat until ready to use in Step 5.

Meanwhile, toss onion wedges, tomatoes, and chickpeas on a baking sheet with a large drizzle of oil, remaining Turkish Spice Blend, a few pinches of salt, and pepper. (For 4 servings, use 2 baking sheets; roast on top and middle racks, swapping rack positions halfway through.)

Roast on top rack, tossing halfway through, until veggies are lightly charred and chickpeas are crispy, 18-20 minutes. (It’s natural for chickpeas to pop a bit while roasting.)

While everything roasts, in a second small bowl, combine hummus, half the parsley and chives, 2 TBSP olive oil (4 TBSP for 4 servings), and juice from one lemon wedge (two wedges for 4). Season with salt. Stir in water 1 tsp at a time until mixture reaches a drizzling consistency.

While everything roasts, pat barramundi* dry with paper towels; season with salt and pepper. Heat a drizzle of oil in a second large, preferably nonstick, pan over medium-high heat. Add barramundi to pan. Cook until cooked through, 4-6 minutes per side.

Fluff rice with a fork; stir in raisins and their pickling liquid and remaining parsley and chives. Season with salt and pepper.

Toss veggies and chickpeas with lemon zest.

Divide rice between shallow bowls or plates. Top with veggies and chickpeas. Drizzle with hummus sauce to taste. Garnish with remaining pistachios and a squeeze of lemon juice to taste. Serve with any remaining lemon wedges on the side.
