Slice halloumi and add to a medium skillet. Cook for 2-3 min per side and then add in a scoop of pesto.
Whisk eggs in a bowl and pour overtop the halloumi once it has browned. Turn burner down to low and let cook for about 2 min or until the eggs begin to set. Add tortilla over top. Using a spatula or a plate, flip.
Add whatever fixins you want on the inside- I did arugula, red onion, avocado and a squeeze of lemon. Fold tortilla and let cook for another 2-3 min or until tortilla is nicely browned on both sides. Slice and enjoy!
