1 Chef's knife, a cutting board, a bowl to place the vegetables in and a clean griller tray, tongs.
Place your Lamb on a dinner plate, and generously coat both sides with the ground Rosemary and Garlic and sprinkle with salt and pepper. Drizzle with Lemon Juice and return to fridge.
In the Bowl, place a quarter of a cup of oil and lemon juice, add good sprinkling of mixed herbs and salt and pepper. Stir and set aside.
Top and Tail the zucchini, slice the capsicums in half lengthways removing the seeds and pulling away the stems. Remove the husk and silk form the corn cobs.

Peel the onions and cut into wedges, placing into bowl.
Add whole unpeeled cloves of garlic to the bowl

Tip the vegetables onto the griller tray and spread evenly.
Griller Tip: If using an electric grill, preheat on medium when starting to prepare vegetables. If using a gas grill, turn on just before placing them under. Place the tray under the griller set on medium.
Heat a fry-pan on the stove on medium and spray with some oil or add a small amount. When heated (after about 2 minutes) add the Lamb.
Keep an eye on the vegetables under the griller so they don't burn. After 5 minutes turn them over using tongs.
After the lamb has cooked on the first turn to seal the other side and cook for another three minutes.
CookingTip:
If your like you Lamb Rare - 2 minutes each side, Medium - 3 - 4 minutes each side and Well Done - 5-6 minutes, turning twice more, cover with a lid. Turning the lamb twice achieves even cooking.
When the vegetables have some colour to them after 5 minutes on each side, turn the griller off and leave.
To Serve:
If using lamb fillet, slice diagonally and place on the dinner plate.
Evenly distribute the vegetables, drizzling some of the juice from the grill tray over them.
