Place a large skillet over medium-high heat. Once skillet is hot, add halloumi and sear on each side for 2 to 3 minutes, or until browned. Remove from heat and cube into bite sized pieces.
Lower heat to medium heat and add butter. Allow butter to melt and toast until lightly browned, 4 to 5 minutes. Add corn and toss together. Saute for 1 to 2 minutes. Season with salt and pepper.
Remove from heat and stir in chives and cilantro.
Fold in cubed halloumi. Finish with fresh lime zest, if using. Serve warm or room temperature.
