Delicious vegetarian halloumi burger. Grilling the tomatoes and peppers really enhance their flavor, as high heat quickly caramelizes their natural sugars and result in slightly charred and juicy tomatoes and peppers.
Slice halloumi cheese and tomato into ½ inch(1 cm) pieces.
Cut the red bell pepper into long strips.
Heat a large griddle pan until hot. Place halloumi pieces and cook for about 1 or 2 minutes on each side until charred lines appear. Set aside.
Add olive oil into the pan and add tomato slices and red pepper strings. Sprinkle salt and a generous amount of freshly ground black pepper and toss to combine. Cook tomatoes slices for 30 seconds up to 1 minute on each side and remove. Remove the pepper strings as well.
Cut the seeded buns and grill until toasted.
Combine the cream cheese with mustard and spread on the bottom part of the bun.
Add halloumi pieces, lettuce leaves, tomato slices and pepper strings. Add red onion rings if desired and finish with the buns top. Serve immediately. Enjoy.
