Place all the ingredients in a bowl and gently toss to combine. Cover and store in the fridge until needed. Can be made a few hours in advance. Gently toss the salsa before serving.
Recipe Options: If you don't care for cilantro, replace it with an equal amount of sliced green onion. Instead of green zucchini, use yellow zucchini, when it is available. To give the salsa a pleasing, smoky and spicy flavour, replace the fresh jalapeno called for in the recipe with one or two finely chopped chipotle peppers. Chipotle peppers are smoked jalapeno peppers that are sold in tins in the Mexican food aisle. Store the unused peppers in a tightly-sealed jar in the fridge.
