I'm a decent cook but have never been good at barbecue (think stuff falling off skewers onto the grill, food that's half charred and half undercooked and so on). We do love grilled veg though (vegetarian household).
Store near me sells fresh veg skewers - so prepped and skewered courgette, onion, capsicum, butternut squash etc. But they have (obviously) not been marinaded. I love the labour and time saving idea of buying pre prepared skewers, but how do I flavour and cook them (oven or stove top)?
