This grilled halloumi salad is a delicious summer main or side dish. It features chewy grilled halloumi cheese, hearty croutons, fresh veggies, and a tangy Greek dressing. This salad is best on the day it's made, but if you'd like to get ahead, you can prep the dressing a few days in advance.
Preheat a grill or grill pan to high heat. Slice the halloumi into ½-inch-thick planks. Rub both sides with olive oil and place on the hot grill. Reduce the heat to medium and grill for 2 to 3 minutes per side, until well-charred. Remove from the grill and slice the planks into cubes.
Assemble the salad with the sliced cucumbers, tomatoes, halloumi, red onions, and croutons. Drizzle with the dressing and top with fresh basil. Season to taste with flaky sea salt, if desired.
