In a medium bowl, combine Lifeway Farmer Cheese, Lifeway Kefir, powdered sugar, vanilla, and salt. Beat until smooth with a hand mixer.
Divide the cream evenly into 4 bowls.
Heat oil in a skillet over medium heat. Once hot, fry each slice of bread in the oil until golden and lightly crisp on both sides, about 20-30 seconds per side. Transfer to a cooling rack and cool completely.
Cut each slice diagonally to form two triangles. Using a small knife, cut a pocket into the center of each triangle (without cutting through the edges).
Fill the pocket with the flavored cream fillings and garnish as noted:
Strawberry flavor: Mix strawberries into 1 bowl of the cream. Spoon the strawberry cream into 2-3 pockets. Garnish with 3 strawberry slices.
Mocha: Stir cocoa powder and espresso powder into 1 bowl of the cream. Spoon the mocha cream into 2-3 pockets. Garnish with chocolate chips.
Churro: Stir cinnamon and brown sugar into 1 bowl of the cream. Spoon the cinnamon sugar cream into 2-3 pockets. Lightly sprinkle cinnamon sugar over the filling.
Tropical: Fold mango and pineapple into 1 bowl of the cream. Spoon the tropical cream into 2-3 pockets. Sprinkle the filling with coconut and more pineapple or mango.
