We don't need an excuse to fire up the BBQ and try new vegetarian BBQ recipes, but this Indian summer we're having is making the idea even more appealing. Mix things up this weekend with a different take on a BBQ lettuce wedge. This one is packed with crunch and flavour. It makes a nice healthy vegetarian alternative if you're thinking of cutting down on meat. Alternatively serve it as a side with burgers. 

Grilled romaine has become a popular BBQ dish recently. This versatile lettuce stays super crispy, and holds its shape, which means you can stuff it chock full of delicious things as well as using it to make a healthier version of a wrap. Quick to do, the main prep with this dish is slicing the vegetables and whizzing up a dressing, and that takes just minutes so it’s not a chore.

  • 1 courgette
  • 1 aubergine
  • 3 king oyster mushrooms
  • 2 romano red peppers
  • 1 romaine lettuce
  • 5g tarragon leaves

For the dressing

  • 10g tarragon, chopped
  • 50g wholegrain mustard
  • 30g white wine vinegar
  • 155g olive oil

For the garnish

  • 20g Parmesan, shaved
  • 10g croutons


1 Slice the courgette, aubergine and king oyster mushrooms approximately ½cm thick. Cut the Romano peppers in half lengthways and remove the seeds and stalk, then cut each half into three pieces.

2 Lightly coat all the vegetables with vegetable oil and lightly season with salt. Grill on the barbecue, cooking vegetables on both sides, until soft and caramelised. Remove the vegetables from the barbecue and place on a tray.

3 To make the dressing, add all the ingredients together in a deep container and emulsify using a hand blender. Use half of the dressing and the whole tarragon leaves to marinade the grilled vegetables, leave for at least an hour.

4 Wash the romaine lettuce leaves while still attached to the root. Carefully prize open the lettuce enough to allow you to fill with the marinated vegetables, making sure you fill all gaps.

5 Once the romaine lettuce has been filled, tie the whole lettuce using butcher’s twine. Place the lettuce on a preheated barbecue. The lettuce should be soft on the outer leaves and slightly warm. Remove from the heat and cut the strings.

6 To serve, use a sharp knife to cut the lettuce in half lengthways. Finish by drizzling some of the dressing on top and sprinkle over some parmesan shavings and croutons. Enjoy!
