In a small bowl, stir together the soy sauce, sriracha, brown sugar, and sesame oil. Set aside.
Next, prepare the veggies so they are ready when needed: Cut the whole cabbage in half and save one half for another recipe. Slice the remaining half in half again, remove the core, and then thinly slice. Peel the carrots, and then use a cheese grater to shred them. Slice the green onions. The garlic and ginger should be minced but placed in a separate pile from the other vegetables.
Heat the oil in a large (12- to 14-inch) skillet over medium heat. Add the ground pork and cook until no longer pink, breaking it up as you go. Add the garlic and ginger, and cook another 30 to 60 seconds or until fragrant.
Add the cabbage, carrots, and green onions to the skillet, and continue to stir and cook until the cabbage is slightly wilted. (I like to keep a little structure to the cabbage, so I cook just long enough to heat it through. You may cook longer to soften further if preferred.) Drizzle in the prepared sauce and stir to thoroughly incorporate.
Sprinkle with nuts or seeds of choice and fresh cilantro, if desired, and pass sriracha at the table for those who like a little extra kick.
