Preheat an outdoor grill to medium-high heat. Grill the corn cobs for 8-10 minutes, rotating a few times until evenly charred.
Remove the corn cobs and set aside on a plate until cooled.
On the hot grill, add the Halloumi cheese and grill for 2-3 minutes per side until there are even grill marks. Set aside to cool.
In the meantime, let’s make the vinaigrette. Add to a small jar, the olive oil, lime juice, mayonnaise, maple syrup, sea salt, garlic powder and pepper. Shake until well combined and set aside for later.
Once the corn is cool to the touch, use a large knife and cut away the corn kernels from the cob.
Dice the grilled Halloumi slices into ½ inch cubes.
In a large bowl add the corn kernels, Halloumi cubes, the bell pepper, the jalapeno, the cilantro, the scallions and your vinaigrette. Mix, cover and place in the refrigerator for approximately 2 hours before serving.
Serve and enjoy!
