Portobellos with tofu scramble

1 Place potatoes on to boil with a little salt and mint for 12-15 minutes until cooked. Place mushrooms and vegetables in a large dish and spray with olive oil.

2 Cook vegetables on the hot grill until lightly seared and cooked. Transfer to a flat barbecue plate, drizzle over balsamic and toss to coat. Transfer to tray above the grill plate to keep warm. Toast walnuts lightly and remove.

3 Heat a non-stick frying pan and add olive oil. Gently fry onion for a few minutes. Add olives and stir through for 1 more minute. Crumble in tofu by breaking up with hands over frying pan. Whisk eggs together with a fork and a little salt. Add to frying pan and cook lightly until mixture moulds together but is still soft.

4 Divide grilled vegetables among 4 plates, place mushrooms cap-side up and top with hot tofu scramble. Scatter over toasted walnuts and serve with potatoes.
