We ate these with Chicken Taquitos and it is awesome. It would also be good with french fries, chicken nuggets, fish sticks, etc.
1/2 cup plain yogurt (I always use greek yogurt)
1/2 cup mayonnaise
1/4 cup milk
3 tablespoons lime juice
2-3 teaspoons dried cilantro (or 2 tablespoons fresh cilantro)
1 tablespoon balsamic vinegar
1 cloves garlic, minced
1 tsp chili powder
Combine all ingredients. Cover and chill until you are ready to eat.
