How to cook
Put the onion, garlic, zucchini and pepper in a large pot or deep pan with a few tbsp olive oil. Fry on high heat until the veggies gain a golden-brown color.
In a separate pan without a lid, put the tomatoes and a little olive oil and cook on moderate heat about 5 min., while stirring periodically.
Cook until the the juice from the tomatoes evaporates. After 5 min., add the tomatoes to the other veggies and stir slightly. Sprinkle with salt and pepper to taste.
