Step 1 Preheat oven to 220°C. Wrap 1 slice of prosciutto around the edge of each beef steak. Secure with a toothpick. Lightly spray all over with cooking oil.

Step 2 Heat a large non-stick frying pan over a medium-high heat. Add steaks and cook for 2 minutes each side or until browned.

Step 3 Place mushrooms in a large roasting pan. Lightly spray with oil. Cook in a preheated oven for 5 minutes. Arrange beef and tomatoes on top and lightly spray with oil. Cook in oven for 12-15 minutes for a medium steak and tender mushrooms and tomatoes. Remove from oven. Cover with foil and set aside for 5 minutes to rest.

Step 4 Meanwhile, wash silver beet and place in a large saucepan. Add cheeses, spring onion and garlic. Cover and place over low heat. Cook, shaking pan occasionally, for 1-2 minutes or until mixture bubbles. Remove from heat and season with black pepper.

Step 5 Spoon silver beet on to serving plates. Top with a mushroom, steak and tomatoes.
