When the beets are cool, slice off the ends and use a vegetable peeler or paring knife to peel the skin. Chop them roughly and put them in your food processor along with a half cup of the Greek yogurt, a teaspoon of lemon juice and the remaining ingredients. Use only one small clove of raw garlic if you don't love garlic, or use more if you do.
½ to 1 cup Greek yogurt, ¼ cup fresh dill, 1 to 3 cloves garlic, 1 tablespoon extra virgin olive oil, ½ teaspoon salt, ¼ teaspoon ground black pepper, 1 to 3 teaspoons lemon juice
