Add olive oil to a large saute pan. When the oil is hot, add the frozen vegetables, together with some salt and pepper.
When the vegetables are soft, add the JUSTEgg and begin scrambling until eggs are cooked (around 2 minutes).
In a separate large bowl, add cooked rice, together with mirin and rice vinegar, as well as the scrambled eggs, and both kinds of toasted sesame seeds.
Place the rice in the refrigerator until it has cooled enough to handle. Then, roll the rice into golf balls.
Stuff the rice balls into the tofu pockets. Sprinkle with additional sesame seeds before serving.
