UFood Grill, the Boston-based fast-casual restaurant group providing a healthy alternative to fast food, announced new UBerry soft-serve yogurt flavors at its Landmark Center/Fenway location in Boston. With probiotic cultures and calcium, protein, and vitamin B, UBerry is fat-free and around 100 calories per 4-ounce serving. The two new flavors—Chocolate and Vanilla—join original flavors Original Tart and Raspberry Tart.

New toppings for the treat include: fresh strawberries, fresh raspberries, fresh blueberries, granola, walnuts, toasted almonds, fruit loops, M&M’s, Reese’s peanut butter cups, chocolate chips, white chocolate chips, chocolate sprinkles, rainbow sprinkles, and crushed Oreos.

To celebrate the new flavors, UFood Grill announced Free UBerry Sundays. During the months of September and October, UFoodGrill will release a password via Twitter every Sunday at 10 a.m. for fans to pass along to a UFood cashier to receive their free UBerry at all Boston locations.
