Preheat the oven to 200°C or 390°F.
Grease a baking dish with 2 tbsps olive oil. Slice larger tomatoes into 3 or 4 slices, about 1cm thick. Halve smaller toms. Layer the tomatoes in the baking dish, season each layer carefully with salt and pepper. Bake for 30 minutes.
Spread the quinoa evenly on a baking sheet. Once the tomatoes have had 30 minutes, add quinoa to the oven & cook both quinoa & tomatoes for 15-20 minutes.
Once the quinoa is crisp and the tomatoes are sticky, arrange the tomatoes carefully on plates. Sprinkle over the quinoa, crumble the feta & tear the olives. Finish with the fresh herbs.
