A Recipe from Sneaky Kitchen
Yogurt Cheese
1  32-oz. carton nonfat, plain yogurt, such as Colombo brand  
1 large yogurt strainer 

Empty contents of yogurt container into yogurt strainer. Set yogurt strainer in large bowl or pan and allow to drain on countertop for at least 5 or 6 hours, or overnight in the refrigerator. Discard whey or save for another use. Yield: 2 cups yogurt cheese.

This yogurt cheese makes a great non-fat "cream cheese" spread or topping.  Add some chives, chopped green onions, grated carrots, dill weed and some garlic salt and you have a great vegetable "cream cheese" spread for bagels.
