Prepare and warm the cilantro lime rice, black beans, chopped steak, and fajita vegetables.
Heat each tortilla in a dry skillet for 15 to 20 seconds per side until warm and flexible.
Place the rice slightly below the center of each tortilla, leaving space around the outer edges.
Add moderate portions of beans, steak, vegetables, salsa, lettuce, cheese, and optional sour cream.
Fold both sides inward, bring the lower edge over the filling, and roll the burrito forward tightly.
Serve immediately or toast the seam-side in a dry skillet for 1 to 2 minutes to help it remain closed.
