• Adjust racks to middle and top positions and preheat oven to 425 degrees. Wash and dry produce. • Trim and dice zucchini into 1⁄2-inch pieces. Halve tomatoes. Strip thyme leaves from stems. Peel and mince garlic. Trim and thinly slice scallions, separating whites from greens. Halve lemon.

• Toss zucchini, tomatoes, and half the thyme leaves on a baking sheet with a drizzle of olive oil, salt, and pepper. • Roast on middle rack, tossing halfway through, until tender, 15-20 minutes.

• Meanwhile, drain and rinse chickpeas; dry thoroughly with paper towels. On a second baking sheet, toss half the chickpeas (all for 4 servings) with a large drizzle of olive oil, paprika, and a pinch of salt and pepper. • Roast on top rack, tossing halfway through, until crisp, 18-20 minutes. (It’s natural for the chickpeas to pop a bit while roasting.)

• While chickpeas roast, heat 1 TBSP butter (2 TBSP for 4 servings), garlic, and scallion whites in a medium pot over medium-high heat; cook until butter has melted and garlic is fragrant, 1 minute. • Add couscous and remaining thyme leaves; stir to coat. Season with salt and pepper. Cook, stirring, until couscous is lightly toasted, 1-2 minutes.

• Add stock concentrate and 3⁄4 cup water (1 1⁄2 cups for 4 servings) to pot with couscous. Bring to a boil, then cover and reduce heat to low. Cook until couscous is tender, 6-8 minutes. • Drain any excess liquid if necessary. Keep covered off heat until ready to serve. While couscous cooks, pat chicken or salmon dry with paper towels; season with salt and pepper. Heat a drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Cook chicken until cooked through, 3-5 minutes per side, or cook salmon (skin sides down) until skin is crisp, 5-7 minutes, then flip and cook until cooked through, 1-2 minutes more. Transfer to a cutting board.

• Add half the veggies, half the feta, and a squeeze of lemon juice to pot with couscous; stir to combine. Season with salt and pepper. • Divide between plates; top with roasted chickpeas and remaining veggies. Garnish with scallion greens and remaining feta. Serve. Slice chicken crosswise. Top couscous with chicken or salmon.
