Add all of the vegetables and cook on medium flame for 2 minutes.
Now add salt, pepper, soy sauce and sriracha. Mix well.
Turn the flame to low, cover the pan and let the vegetables cook for about 4-5 minutes.
Take off the lid and stir the vegetables. Let cook for additional 4-5 minutes until fully reduced and lightly browned.
Turn off the flame and transfer this mixture to a plate lined with kitchen paper to get rid of excess oil. Place additional kitchen paper on top of the veggies to absolutely get rid of any moisture and oil. Press the kitchen paper on the veggie mix so that all oil is absorbed in the kitchen paper.
Prepare the spring rolls (see step by step method in blog post) and deep fry until golden brown.
