Prepare rice according to package directions. Transfer the rice from the pouches to a shallow bowl to cool.
Heat oil in a medium nonstick skillet over medium heat. Add vegetables and sauté until crisp-tender, 4 to 5 minutes. Add teriyaki sauce; toss well to coat the vegetables. Remove from heat; set aside.
Divide the cooled rice among 4 single-serving containers. Top each with one-fourth of the vegetables. Divide tofu among the containers. Seal and refrigerate for up to 4 days. Vent the container and microwave until steaming before serving.
