Peel half of the cucumber lengthwise, leaving strips of peel on the other half. Grate or finely chop the cucumber, then squeeze out any remaining liquid from the cucumber.
In a medium bowl, combine the dried cucumber, vegan yogurt, lemon juice, garlic, dill, salt, and pepper. Mix well until all the ingredients are evenly distributed.
Cover the bowl with plastic wrap and refrigerate the tzatziki for at least 30 minutes to allow the flavors to meld. Serve chilled and enjoy.
Notes
Use a thick Greek-style vegan yogurt for the best results. Don't use one that has added flavors or sweeteners.
Drain the cucumbers after grating to avoid a watery sauce.
Fresh dill can be substituted for ½ a tablespoon of dried dill.
This sauce can be made up to 2 days ahead of time.
To Store: Keep refrigerated in an airtight container for up to 3 days. Stir well before serving.
