Narrative:
Upon selecting flaps 30 and running the before landing checklist; we realized the trailing edge flaps were frozen symmetrical between flaps 25 and 30. The approach was continued with no roll or adverse aircraft handling. A normal landing was executed adding a few knots (approximately Vref15). Upon further review; a go-around should have been executed; the appropriate checklist in the QRH run; and then returned for the approach and landing.
