Put the potatoes into a pan of cold water. Bring to the boil and simmer for approx. 15 minutes until the potatoes are tender. Drain and set aside to cool.
Meanwhile, put the garlic and onion onto the BBQ and gently grill them until soft. Set aside.
Cut the courgette, red & yellow pepper into thick slices or chunks. Put them on the BBQ and cook until charred. Place them into a large serving bowl and cover.
Finally barbecue the cherry tomatoes until tender (this should only take a minute or so) and add to the other vegetables.
Remove the skins of the garlic and onion. Remove the skin of the peppers (optional). Cut the onion and peppers into thin slices and add these to the courgette.
Cut the potatoes in half (if they are too big) and char them on the BBQ (optional) and place them in the bowl.
Toss everything in the serving bowl, then drizzle a little some olive oil and cider vinegar over the veggies. Season to taste, then toss again. Taste and adjust the oil, vinegar and seasoning, then cover the salad until you’re ready to serve.
Add the chopped herbs just before serving.
