In a very hot pan, add some olive oil and pan fry the vegetables by batches for 3 mins each: onions & garlic / green & red peppers / aubergine & cougette. Then put all together into a suitable casserole.
Pan fry the tomatoes for 2 mins and add the white wine, then add it into the casserole with the rest of ingredients.
Bring to boil all the ingredients combined with seasonings, then reduce temperature to a simmering and cook for 30 mins with a lid on.
For serving: Place pisto onto a plate and add a poached or fry egg.
Note: You can add a raw egg onto the pisto and finish it in the oven, but make sure the plate is suitable for oven.
