1. Cut the cherry tomatoes in half, or into quarters if they are large, and place them in a bowl. Add the halloumi, garlic, and drizzle with olive oil. Sprinkle with salt, pepper, fresh thyme, and oregano, and mix. Place them on a baking tray and bake in a preheated oven at 200°C for 40 minutes. Meanwhile, put the water in a saucepan, cover with the lid, and let the water come to a rolling boil. Add the salt and the stock cubes. Stir and add the pasta. Let the broth boil again and cook for 8 minutes. Turn off the heat and drain the pasta. Keep 1 cup of the cooking liquid.
For the Pesto:
1. In a small pan, toast the pine nuts on all sides. Let them cool. In a small blender, place all the ingredients for the pesto. Blend well. Return the pasta to the saucepan and add the mint pesto and the reserved cooking liquid. Mix well and add the roasted cherry tomatoes. Stir gently and serve. If you like, add extra grated halloumi cheese.
