  • 12" Fry Pan
  • Tongs
  • Spatula/Turner
  • Sharp Knife & Chopping Board
  • Paper Towels


  • 4 large thick slices of Bread
  • 1x 8oz/225g block of Halloumi, divided into 8
  • 3.5oz / 100g Chorizo, thinly sliced (with casing removed)
  • 1/2 cup / 50g Mozzarella, shredded
  • 1 small Avocado, sliced
  • 2 tbsp Sun Dried Tomato Pesto (see notes)
  • Butter, as needed

Optional, to serve:

  • Rocket/Arugula
  • Sour Cream


  • Soak up as much moisture as you can from your 8 slices of halloumi with paper towels. Place in a pan over medium-high heat and fry both sides until golden. If your pan is non-stick you won't have to add oil (can still add a touch), if it's not, I recommend using oil.
  • Butter both sides of 2 slices of bread and place butter side down on a chopping board. Add halloumi slices, followed by chorizo, topped with sun dried tomato pesto, followed by avocado and finished with mozzarella. Top with another slice of bread and spread butter over the top.
  • Place in a pan over medium heat and fry both sides until golden, carefully flipping in between. Serve with rocket/arugula and a dip of sour cream!



a) Halloumi - I find the halloumi releases less moisture when it's at room temp, so if you've got time I recommend doing that. Oil is optional depending on your type of pan, but I do usually add a dash to get things going.
b) Sun Dried Tomato Pesto - Can use store bought (widely available in most supermarkets), or use my homemade recipe! Just a note though, I recommend reducing the salt as both halloumi and chorizo are quite salty. Roasted red pepper pesto also goes great in this sandwich, just same again with the salt. If you're looking for subs, I haven't actually used either of these, but I'd imagine regular basil pesto or just sun dried tomatoes and basil leaves would work great!
c) Calories - per sandwich with no sides.
