Preheat the oven to 180°C conventional (160°C fan-forced). Line a tray with baking paper.
Spread the cherry tomatoes and olives on the tray, drizzle with some olive oil and season well. Roast for about 30 minutes until soft. Set aside.
1/2 cup cherry tomatoes, 1/2 cup kalamata olives, extra virgin olive oil, sea salt & cracked black pepper
Spray the pieces of bread with some olive oil spray and toast in the toaster or under the oven grill for 5 minutes.
4 pieces ciabatta, olive oil spray
Lay the toasted bread on a tray. Layer with the tomato paste, ricotta, spinach, salami pieces, cherry tomatoes, olives, mixed herbs and feta. Place under a hot grill for 7 minutes (just watch they don't burn). You can also bake in a hot oven for about 15 minutes.
Drizzle over some olive oil, scatter with basil leaves and season well.
extra virgin olive oil, basil leaves
Notes
The mixed herbs I used are from the fruit/veg section of the supermarket. They are in a sachet and are lightly dried (so they last for 4 weeks in your fridge). Mine were a mix of parsley, basil and oregano, but you can use any fresh or dried herbs you have, or just basil!
