Often times, packaged cooked noodles are vacuum sealed, so the noodles are compressed into solid bricks. To break the noodles apart, remove the noodles from packaging and microwave them for about 1 minute 30 seconds on high. When the noodles are cool enough to handle, use your fingers to break the noodles apart.

Heat 1/2 tablespoon of olive oil in a large sauté pan over medium-high heat. Add the green beans and cook them for about 1 minute. Add a few tablespoons of water to the pan to keep green beans from burning. Continue cooking the beans for about  4 to 5 more minutes, until they turn bright green. 

Add more water to the pan if it is looking dry. Season the green beans with a small pinch of salt and transfer the beans to a plate.

Wipe down the pan and heat the remaining olive oil over medium-high heat. Add the garlic, ginger, and scallions and cook them for 1 minute. Add the tomatoes, salt, cumin, and the red pepper flakes (if using). Cook the tomatoes for about 5 minutes, until they start to break down.

Add the noodles, cooked green beans, and soy sauce to the pan. Toss everything together so that the noodles are covered in the soy sauce and tomato mixture. Cook the noodles for a few minutes until they are heated through. Taste and season the noodles with more salt or soy sauce, if necessary.
