Preheat oven to Combi Steam, 350°F/180°C, 50% (medium) humidity.
Put the chicken and potatoes onto the largest sheet pan or baking dish that will fit in your oven; the more space the better as it allows all your ingredients to cook faster and more evenly.
6 medium chicken thighs, 4 small potatoes
Mix the olive oil, garlic, smoked paprika, oregano, vinegar, salt and pepper in a small bowl. Pour half of this mixture onto the chicken and potatoes, then toss together so they're well coated. Spread everything out into a single layer with the skin side of the chicken facing up, then put the pan into your oven and cook for 12 minutes.
1/3 cup olive oil, 3 cloves garlic, 1 1/2 tsp smoked paprika, 1/2 tsp oregano, 1 tbsp red wine vinegar, 1/2 tsp salt, 1/2 tsp pepper
While the chicken and potatoes get started in the oven, put the torn bread, cherry tomatoes, chorizo and olives in a large bowl and toss with the remaining olive oil mixture.
1/2 loaf stale bread, 14 oz cherry tomatoes, 2 chorizo sausages, 4 oz green olives
When the timer goes, add the bread, tomato and chorizo mix to the pan, spreading everything around so it's single layer and in between the chicken and potatoes. If you can't quite fit everything in one layer, make sure the bread and chorizo are at the top; it doesn't matter so much if some of the tomatoes and olives are a little covered.
Return the pan to the oven until the chicken is cooked and golden-skinned, the potatoes are tender and the chorizo and bread are crisped on top. Depending on the thickness of the meat and your pan, this will take 15-20 minutes.
Serve immediately; I put the whole pan on the table with warmed plates and let people help themselves.
