Frozen Fruit Yogurt Pops

2 medium-size mangoes, halved, peeled,
    pitted and cubed (about 2 cups)
2 tablespoons frozen fruit juice concentrate, any flavor
2 cups low fat vanilla yogurt (not custard-style)
8 (3 ounce) paper cups
8 Popsicle sticks
8 foil squares

Combine mango and juice concentrate in blender. Whirl until smooth. Stir together puree with yogurt in medium-size bowl. Add sugar to taste if mixture is too tart. Divide mixture evenly among paper cups. Cover cups with foil squares. Pierce foil with paring knife to make slit small enough to hold the Popsicle stick upright. Carefully insert stick through top of foil into yogurt mixture. Freeze overnight or until solid.

NOTE: For the mango, you can substitute 4 ripe kiwifruit, peeled and cubed, or 2 cups blueberries.
