Grate the cucumber using a cheese grater. Then sprinkle some salt over top and mix it. The salt will help the excess moisture to seep out. Set aside.
Add the Greek yogurt to a separate bowl along with the lemon juice and minced garlic.
Squeeze the cucumber so to get rid of the excess moisture. Discard the cucumber water. Add the drained cucumber to the yogurt mix and give it a good mix.
Let it sit in the refrigerator for at least 15 min so the flavors blend. Enjoy!
Notes
The tzatziki sauce will last for at least a week (usually much longer) if kept in an airtight container in the fridge.Use this sauce as a dip for pita, pita chips, fresh vegetables (can be a healthier ranch substitute). Or as a condiment on top of scrambled eggs, on gyros, or chicken shawarma.
