Working quickly, roll out 1 sheet of phyllo onto a clean work surface. Mist with cooking spray. Place a second sheet on top and mist again with cooking spray.
Cut phyllo lengthwise into 4 strips (each about 3 1/4-inch wide).
TIP: Cut phyllo in half lengthwise, then halve each section again for 4 even strips; no measuring required!
Place 1/4 cup filling onto 1 end of 1 strip.
Fold corner over filling to opposite side of strip, making a triangle.
Fold triangle up to meet straight side, then across again. Continue folding over triangle until you reach end of phyllo strip.
Mist with cooking spray. See our complete Phyllo Bites recipe here.
