Chicken Avocado Roll-Ups

In a medium bowl, combine avocado and lime juice and mash until only small chunks of avocado remain. Add chicken, bell pepper, red onion, Monterey Jack, cheddar, sour cream and chives and stir until evenly combined. Spread a thin layer of the chicken avocado mixture onto a large tortilla, leaving a small border around the edges. Roll the tortilla up tightly, then cut off the edges and slice into 1” rolls. Repeat with remaining ingredients. Serve cold or at room temperature.
