Step 1

Rinse all the vegetables and cut them into chunks (cut button mushrooms in half; cut onion into quarters and separate the layers; cherry tomatoes can be cut in half or left as whole)

Step 2

Place all the veggies apart from cherry tomatoes onto a baking tray/sheet or disposable aluminum tray. Season them with salt, pepper, oregano and olive oil and mix everything well, making sure all the veggies are coated with the seasoning.

Step 3

Grill for 10 minutes, stirring from time to time. Then add cherry tomatoes and grill for a further 10 minutes or until the vegetables are to your liking.
