Mix soy sauce, ketchup, sriracha, black pepper and salt in a small bowl and keep it aside.
You can use the left over oil in the same pan or add a tablespoon of oil to a different pan on a medium heat.
Once oil is hot add ginger, garlic and green chilies and saute for 30 seconds, until the raw aroma goes away.
Increase the heat and add scallions, bell pepper and celery and stir until all veggies are nearly cooked. If you take a bite, there should be a slight crunch.
Stir in the soy sauce mix.
Next add fried gobi and mix until all florets are completely coated.
Lastly add vinegar and give everything a nice last stir.
Garnish with scallion greens. Best served with fried rice!
