How to make Tabbouleh Salad

My take on this Middle Eastern salad. This can be made with whatever ingredients you like. I choose to use what I have;
1/2 a large Cucumber
4 small Tomatoes
1 sweet Onion
1 cup Parsley
1/2 Cup Cilantro
1/2 Cup Sunflower Seeds lightly toasted and salted
4 tablespoon Olive Oil
Salt and Pepper to taste
Mix all ingredients together in a large bowl. Serve with your favorite dish. Best if allowed to marinate for 1 hr.
Hope you all enjoy it.
