Step 1

Preheat oven to 180°C. Heat 1 tablespoon oil in a large non-stick frypan on medium-high heat. Cook seasoned chicken 2 minutes each side until golden. Roast on a baking tray for 10 minutes until cooked. Cover to keep warm.

Step 2

Meanwhile, heat remaining 1 tablespoon oil in the same pan over medium heat. Cook onion for 5 minutes, add garlic, capsicum and mushroom, then cook for 5 minutes more. Add tomato, paste and oregano, and cook for 5 minutes. Add liquid, bring to the boil, then reduce heat and simmer for 5 minutes to thicken slightly.

Step 3

Top chicken with cheese, then melt in the oven for 1 minute. Serve topped with sauce and garnished with extra oregano.
