Mix cream cheese, sour cream, green onions, and taco seasoning in a bowl until well blended.

Spread a thin layer of cream cheese mixture onto each tortilla. Roll each tortilla tightly to create a long tube. Spread more cream cheese mixture on the edges of each tortilla to seal.

Freeze rolls on a baking sheet for 20 minutes for easier slicing. Cut each roll into 1-inch pieces and thaw before serving.
