Place chicken and Marinade into a bowl and set aside to marinate for at least 3 hours to overnight.

Thread chicken onto 8 skewers.

Heat oil in a large skillet over high heat (or BBQ). Cook skewers for 3 minutes on each side, or until cooked through.

Serve Chicken Souvlaki with tzatziki, flatbreads (make your own!), lettuce and tomato slices.

Cut the cucumber in half lengthwise. Use a teaspoon to scrape the watery seeds out. Coarsely grate the cucumber using a box grater. Then wrap in paper towels or a tea towel and squeeze to remove excess liquid.

Place cucumber in a bowl. Add remaining ingredients then mix to combine. Set aside for at least 20 minutes for the flavours to meld.
