Prep the squash. Pat the slices dry with a clean towel.
Toss with 2 tablespoons olive oil, 1/2 teaspoon salt, and the black pepper. Dry squash browns better, so don’t skip this step.
Make the dressing. In a small bowl, whisk lemon zest, lemon juice, garlic, honey, red pepper flakes, and a pinch of salt. Set aside.
The balance should be tangy with a soft sweetness.
Heat the pan. Set a large cast-iron or heavy skillet over medium-high heat. Lightly oil the surface. When it shimmers, it’s ready.
Char in batches. Add a single layer of squash.
Cook 2–3 minutes per side until you see deep golden spots and the edges start to soften. Don’t stir too much. Transfer to a large bowl and repeat with remaining squash, adding a touch more oil as needed.
Toss while warm. Sprinkle the remaining 1/2 teaspoon salt over the warm squash.
Drizzle on the dressing and gently toss. Warm vegetables absorb flavor faster, so work quickly but lightly to keep slices intact.
Add the good stuff. Fold in half the herbs and half the nuts. Taste and adjust with a pinch more salt or a squeeze of lemon if needed.
Plate with creaminess. Spread the yogurt or labneh on a serving platter.
Mound the dressed squash on top. Scatter over the feta, remaining nuts, and remaining herbs. Finish with a thread of extra-virgin olive oil.
Serve. Enjoy warm or at room temperature.
It pairs beautifully with anything grilled.
