In small bowl mix together shredded chicken and pesto sauce.
To assemble taco: Spread about 2 teaspoons Ranch dressing on one flour tortilla, then down center place about ½ cup shredded chicken, and ¼ cup shredded cheese. Roll up or fold in half to serve. Repeat with remaining tortillas and ingredients.
If desired, tortilla can be folded in half, placed on medium high hot skillet, then cover and cook first side for 40 seconds; turn over tortilla and cook second side for additional 30 seconds. Remove from heat and cut in half.
