Murcia's garden-fresh vegetable medley: tender courgettes, sweet fried onions, and ripe tomatoes slow-cooked together in extra virgin olive oil until rich, glossy, and caramelized.
Heat olive oil in a wide frying pan over medium-low heat. Add chopped onions with a pinch of salt, cooking gently for 15 minutes until sweet, soft, and lightly golden.
Add diced courgettes to the pan. Sauté over medium heat for 12 minutes until tender and lightly colored.
Add chopped tomatoes, sugar, salt, and pepper. Cook over low heat for 18-20 minutes, stirring frequently until the sauce reduces into a rich, glossy, thick pisto.
Adjust salt to taste and serve warm or at room temperature with plenty of rustic bread.
