Cut the block of halloumi on the long edge into four slices of equal size. Remove the step of the mushrooms to allow them to lay flat on the grill when the open side is down. Rub the portobello mushrooms with olive oil, salt and pepper.

Heat a grill to medium-high. Grill mushrooms for about 12 minutes. Halloumi takes 5 minutes to grill on both sides. Avoid direct heat, and ensure that the grill bars are not far apart as the halloumi may fall between.

While the portobello mushrooms and halloumi are grilling, combine the mayonnaise, sliced red pepper, garlic and the juice of half lemon in a blender or food processor until smooth.
