Wash the zucchini. Slice, remove the seeds and cut into chunks set aside.
Chop the tomatoes and onion set aside.
Heat two tablespoons of olive oil in a pan on medium heat. Add the garlic and parsely and saute for a few minutes. Don't burn the garlic. Next, add the tomatoes, onion and zucchini to the pan. Saute on medium high heat for 8-10 minutes. Add salt and pepper to taste. Continue to cook until the zucchini are cooked, but still have some crunch.

Notes
If the pan starts to dry out, add two tablespoons of water to the pan and cover for two minutes.
