Cut each pita fold into 8 wedges. Insert pretzel stick half into center of bottom of each wedge to form “tree trunk.” In small bowl, mix sour cream, guacamole, parsley and garlic-pepper blend. Spread about 1 teaspoon sour cream mixture on each pita wedge. Blot bell pepper with paper towel to remove excess moisture. Sprinkle about 1/4 teaspoon bell pepper on each wedge or arrange to form a garland. If desired, cover and refrigerate up to 8 hours before serving.
