Make the pesto. In a food processor, pulse garlic and pine nuts. Add in olives, parm and olive oil. Season with salt and pepper. Taste and adjust accordingly.
Slice halloumi and add to pan on medium heat. Once cheese gets nicely golden, flip and repeat. You don’t need to add any oil to the pan!
Coat bread in olive oil and cook in a pan for about 2-3 min per side.
Spread pesto on toast with halloumi slices and tomatoes. Season with red pepper flakes if you want some spice. Enjoy!
