Have you ever thought about grilling cheese-not in a sandwich, but as a big, glorious slab right on the heat? The outside gets beautifully charred while the inside turns warm and melty. It’s a revelation! This recipe pairs that crispy, herby cheese with fluffy whole wheat couscous and tender zucchini and onion dusted with tangy sumac.
The star is the za’atar crust, a Middle Eastern blend of sesame, thyme and sumac that adds incredible flavor. Served over a bed of couscous with roasted veggies and fresh basil, this dish is simple enough for a weeknight but impressive enough for guests. Ready in about 30 minutes, it’s a vegetarian dinner that will surprise and delight.

Ingredients
Instructions
- Wash and dry all produce. Preheat broiler to high or oven to 500°F. Halve zucchini lengthwise, then cut into long, thin wedges. Halve and peel onion, then cut into 1-inch-thick wedges. Finely mince 1 wedge. Zest lemon until you have 1 tsp zest, then cut into wedges. Halve tomatoes. Pick basil leaves from stems; discard stems. Thinly slice leaves.
- Heat a drizzle of olive oil in a small pot over medium-high heat. Add minced onion and couscous. Cook, tossing, until onion is softened and couscous is lightly toasted, 2-3 minutes. Pour in 1 cup water and stock concentrate. Bring to a boil, then lower heat, reduce to a simmer and cover. Cook until tender, 10-12 minutes.
- Toss zucchini, onion wedges, sumac and a large drizzle of olive oil on a baking sheet. Season with salt and pepper. Broil (or bake) until lightly charred, 10-15 minutes, tossing halfway through.
- Heat a drizzle of olive oil in a large pan over medium-high heat (use a nonstick pan if you have one). Take 4 oz grilling cheese (about half the package; we sent more than needed) and cut into 2 large slices. Place za’atar on a plate. Press cheese into za’atar to evenly coat all over. Add to pan and cook until browned, 2-3 minutes per side.
- Transfer couscous to a large bowl once done simmering. Stir in tomatoes, half the basil, a squeeze of lemon juice and lemon zest. Season with salt and pepper.
- Divide couscous between plates. Top with zucchini, onion and grilling cheese. Garnish with remaining basil and serve with remaining lemon wedges on the side for squeezing over.
Recipe Tips
Use a nonstick pan for the cheese to prevent sticking.
If you can’t find grilling cheese, halloumi is a great substitute.
For extra char, broil the veggies on the top rack.
FAQ
Can I use a different type of cheese?
Yes, halloumi or paneer work well as substitutes for grilling cheese.
What if I don't have sumac?
You can substitute with a squeeze of lemon juice and a pinch of salt, but sumac adds a unique tangy flavor.
Can I make this dish ahead of time?
The couscous and roasted veggies can be made ahead, but the cheese is best cooked fresh to maintain its crispy crust and melty interior.
