Preheat the oven to 200ºC.
Arrange the peppers, shallots and garlic on a foil-lined baking tray and rub with a little oil.
Roast for 25 minutes, turning once, until the skins blister and char.
Remove the peppers from the oven and transfer them to a shallow bowl.
Cover with cling fi lm and leave to steam for 10 minutes, which loosens the skins and makes them easier to peel.
Continue roasting the garlic for another 5 minutes, then transfer it to a different bowl.
Lower the oven temperature to 160ºC. and continue roasting the shallots for a further 10 minutes, then remove them from the oven and add to the bowl with the shallots.
When all the vegetables are cool enough to handle, peel away the skins from the peppers and pull out and discard the seeds and membranes.
Slice the peppers into wide strips, making sure you retain any of the roasting juices.
Squeeze the garlic out of its skins and set aside to make the dressing.
Peel away the shallot skins and slice the soft roasted fl esh in half.
Transfer all the roasted vegetables, together with any juices, to a mixing bowl.
Heat a tablespoon of oil and a tablespoon of butter in a frying pan and saute the courgette slices over a medium-high heat for a few minutes, turning regularly, until they colour a deep golden brown.
Transfer to the mixing bowl, along with the roasted tomatoes.
Add a little more butter and oil to the pan and heat to a sizzle.
Add the Turkish bread and season with salt and pepper.
Fry over medium heat, turning regularly, until it starts to crisp and colour.
Add the pepper paste and saute for a further 3-4 minutes, until the bread has absorbed the paste and colours a reddish brown.
Remove from the pan and set aside for a moment.
Lower the heat and add the extra-virgin olive oil to the pan.
Add the reserved garlic and the capers and saute for a minute or two, squishing the garlic to a paste.
Don’t allow it to brown.
Add the sherry vinegar and lemon juice and increase the heat to a simmer.
Let it bubble for a few minutes then pour onto the vegetables.
Add the bread to the bowl, along with the basil leaves and lamb’s lettuce, and toss everything together very gently.
Taste and adjust the seasoning if need be, then serve warm or at room temperature with cool, creamy yoghurt.
