Prepare your noodles as per package directions. Drain and toss with 2 Tbsp butter or oil after cooking and let melt so it doesn't stick together.
Heat 2 Tbsp of oil in a wok or frying pan and add the sliced onions and fry until soft and translucent, add the garlic and ginger and toss for another minute or so.
Add ground meat to the fried onions, garlic and ginger and break up and toss until cooked through.
Add the soy, gochujang paste, tomato paste, and honey and mix well, heat for 2 minutes.
Add the stir fry vegetables, cooked noodles, rice vinegar, pepper flakes, toss in the meat mixture, cover and cook for 5-8 minutes.
Drizzle with sesame oil and serve!
Feel free to finish if off with a bit more soy sauce and sriracha for extra salt/spice.
