Feeling like making something easy and cheesy? Enter the halloumi and mushroom burger. Mushroom and halloumi are hearty meat substitutes which can please even the most committed meat lover. We love mushrooms for their earthy flavour, and they’re super healthy with lots of vitamins and minerals. This burger is lifted with yummy grilled capsicum and fresh veg. The gorgeous caramelised onion gives it all that extra depth and sweetness.

On different occasions we have used both our Olympus Minted Halloumi and our Olympus Buffalo Halloumi. Both are equally delicious!

Experiment with your favourite burger bun. Try a Turkish bun, ciabatta bread or a brioche. If you aren’t eating carbs, this is equally good as a stack – you could also add in some grilled zucchini or grilled eggplant – or both.

Top it off with a creamy basil dressing, or if you’re keen for some heat, it goes beautifully with smoked chilli honey. Try a local favourite, Blended blazed smoked chilli honey. This goes beautifully with our minted halloumi…but beware the heat!

Mushroom and Halloumi Burger

It's advisable to have everything sliced and ready to go, so that you can build your burger as soon as the halloumi is cooked. If you're adding basil mayo, mix the mayo with pesto and set aside.
