The kale here becomes very crunchy and charred, almost like toasted and crumbled nori, and nicely contrasts the soft texture of the squash, with the red pepper flakes and crumbled feta adding a spicy and salty balance to its sweetness.
You could also serve this with cooked farro or pearled couscous for more of a grain bowl situation, with some sliced avocado on top. Sumac has a bright, lemony taste and can also be sprinkled directly on the vegetables, before or after cooking, if you’d like, or skip it and add a bit of lemon zest and a touch more salt to the tahini spread.
Note: If you’re going to plate the vegetables, then you can spoon the spread onto the bottom of the plate, then place the vegetables on top rather than serving it on the side. Store any leftover sauce covered in the refrigerator for up to a week, freshening it up with lemon juice before serving. —yasminfahr
4 as a side
(about 5 to 6 ounces) delicata squash, ends trimmed, seeds removed and sliced into 1/2-inch-thick half moons
lacinato or curly kale, leaves removed from the stems and torn into 1-inch pieces
extra-virgin olive oil, plus more for drizzling
to 1/2 teaspoon red pepper flakes, plus more to taste
plus 1/2 teaspoon kosher salt, plus more to taste
freshly squeezed lemon juice (from 2 lemons)
ground sumac, plus more for sprinkling on top
cracked black pepper
packed flat-leaf parsley leaves and tender stems, roughly torn (optional)
Heat the oven to 400°F with a rack positioned in the lower third of the oven.
On a sheet pan, coat the squash and kale with the olive oil, then season with the cumin, red pepper flakes, and salt, until everything has a glossy sheen to it. Be sure to squeeze the kale leaves with your hands as you mix. Arrange the vegetables on the sheet pan, ensuring the squash pieces have contact with the pan and arranging the kale in empty spaces. The pan will be a little crowded, but the kale leaves will quickly shrink.
Roast in the oven until the squash is easily pierced with a fork and the kale crispy, 25 to 30 minutes, turning the squash over and mixing around the kale halfway into the roasting time.
Meanwhile, in a small serving bowl, whisk the tahini with the 1/4 cup water until it becomes a smooth, spreadable hummus-like consistency. Whisk in the juice of 1 lemon (about 2 tablespoons), sumac, and 1/2 teaspoon salt. Loosen with more lemon or water if needed, or add more tahini to thicken. Sprinkle some sumac on top, if desired.
Remove the vegetables from the oven. Pour the remaining lemon juice on top, drizzle with olive oil, and top with the crumbled feta, pepper, and parsley, if using. Serve with the sumac-tahini sauce
