Halloumi and sweet potato burgers with chilli, mint and mashed avocado

Swap the meat for salty halloumi and roasted sweet potato and add some mint and lime to keep everything tasting fresh and vibrant.

Slices of halloumi and sweet potato are marinated, grilled and placed in burger buns spread with a generous amount of smashed avocado, making this the perfect vegetarian BBQ dish. If you're short on time, you can skip the marinating step, but it really adds an extra dimension to the dish.

What you'll need...

  • 250g halloumi, sliced into 8 pieces
  • 2 sweet potatoes, peeled and sliced into rounds
  • 1 red chilli, chopped
  • Handful of fresh mint, chopped
  • 1 lemon, juice and zest
  • 1 large avocado
  • 2 tbsp mayonnaise
  • 2 red peppers, sliced
  • 4 burger buns
  • Handful of rocket
  • Juice of 1 lime
  • Handful of fresh coriander, optional

Method

  1. Put the halloumi and sweet potato in a mixing bowl with the chilli, mint, lemon zest and juice and a glug of oil. Leave for 30 minutes to marinate.

  2. Smash the avocado with the mayo, coriander (optional), lime and some salt and black pepper.

  3. Heat a barbecue or griddle pan, then cook the sweet potato for 5 minutes on each side or until charred and tender. Cook the halloumi for 1 minute on each side or until charred and to your liking.

  4. Spread the smashed avocado onto the toasted bun bases, then top with halloumi, sweet potato and roasted red peppers. Scatter over the rocket or basil, add the bun tops and serve straight away.
