Tzatziki

1/2 cucumber
1 cup plain Greek yogurt (or strain normal yogurt to make it thicker)
2 cloves garlic, minced
1 Tbls. chopped mint leaves, or dill weed
pepper as desired

Cut the cucumber in half lengthwise and remove the seeds. Grate the cucumber into a bowl. Stir in all the other ingredients.

It gets better as the flavors combine over time (like 30 minutes), but you can use it immediately.
