To make the Tzatziki, grate the cucumber and drain the water slightly in a paper towel. Mix the cucumber with the yoghurt, lemon juice, garlic and salt and pepper. Add more lemon, garlic or pepper for a lighter flavour if desired.
Slice tomatoes, cucumbers, lettuce and parsley and toss with spices and lemon juice or olive oil if desired. Assemble the salad with pita chips, hummus, felafels and the coconut tzatziki and enjoy!
