Ingredients for Grilled summer squash and red onion with feta
120 ml extra-virgin olive oil, plus more for grilling
1 garlic clove, finely grated
60 ml white wine vinegar
4 medium courgettes, cut lengthwise into 0.5 cm thick slices
1 medium red onion, cut through root end into 8 wedges
2 bay leaves
kosher salt, freshly ground black pepper
225 g feta, crumbled into large pieces
4 banana peppers from a jar, thinly sliced crosswise
generous pinch of crushed red pepper flakes
How to make Grilled summer squash and red onion with feta
Preheat the grill to medium-high heat and lightly oil the grate.
Whisk together the garlic, vinegar, and 120 ml of oil in a small bowl to create the marinade; set it aside.
Toss the squash, onion, and bay leaves on a rimmed baking tray with the remaining 45 ml of oil to coat, then season generously with salt and black pepper.
Arrange the squash and onion on the grill. Grill the squash undisturbed until grill marks appear, about 3 minutes. Turn the squash over and grill the second side until tender and starting to release liquid, about 2 minutes. Transfer the squash back to the baking tray.
Grill the onion, turning occasionally, until tender and charred around the edges, about 5 minutes. Transfer the onion back to the baking tray.
Arrange the grilled squash, onion, bay leaves, and feta on a rimmed platter, then pour the reserved marinade over the top.
Scatter the banana peppers on top and sprinkle with red pepper flakes. Allow to sit for at least 15 minutes and up to 1 hour before serving.
