Method:
You will also need two 12-inch (30 cm) flat metal skewers.
Begin by cutting pepper and onion into even-sized pieces about 1 inch (2.5 cm) square, to match the size of cubes of cheese. Then chop herbs and garlic quite finely and combine them with the oil, lime juice and some freshly milled pepper. Now place cheese, onion, pepper and mushrooms in a large, roomy, non-metallic bowl and pour marinade over them, mixing very thoroughly. Cover and place in the fridge for 24 hours, and try to give them a stir round every now and then.
When you're ready to barbecue kabobs, try the two skewers and thread a mushroom on first (pushing it right down) followed by a piece of onion, a piece of pepper and a cube of cheese. Repeat this with more onion, pepper and cheese, finishing with a mushroom at the end. Place the kabobs over the hot coals, turning frequently till they are tinged brown at the edges, about 10 minutes. Brush on any leftover marinade juices as you turn them.
