Wash and dry all produce. Preheat oven to 400 degrees. Bring a medium pot of generously salted water to a boil. Peel carrots and halve lengthwise, then slice crosswise into 1/2-inch-thick pieces. Halve, core, and seed bell pepper, then cut into 1/2-inch-wide strips. Halve, peel, and thinly slice shallot. Chop parsley. Zest lemon, then halve; squeeze juice into a small bowl.

Toss bell pepper and carrots on a baking sheet with a drizzle of olive oil, a pinch of salt and pepper, and 1 to 2 tsp harissa, depending on how much spice you like. Roast in oven until tender, about 20 minutes.

Once water is boiling, add freekeh to pot. Boil until tender, 20-25 minutes. Drain and return freekeh to pot.

Place shallot in another small bowl with 1 TBSP lemon juice, a pinch of salt, and a pinch of sugar. Toss to coat. Set aside to marinate. Place pistachios, a drizzle of olive oil, and half the za’atar in a small pan. Place pan over medium-high heat and toast pistachios, tossing frequently, until aromatic and a warm golden-brown shade, about 5 minutes.

Mix lemon zest, a large pinch of salt, and 2 TBSP olive oil with remaining lemon juice in bowl. In another small bowl, stir together yogurt, feta cheese, and remaining za’atar. Stir in water 1 tsp at a time until mixture has a consistency that’s thick and creamy but not stiff.

Pour lemon dressing over freekeh in pot and stir to coat. Divide between plates, then arrange veggies on top. Dollop with feta sauce. Garnish with shallot, pistachios, and parsley.
