Arrange pork in a bowl. Add salt, sugar, pepper, garlic and ginger. Mix well.
Add cornstarch and soy sauce. Continue to mix until all ingredients are well blended.
Heat oil in a pan. Once the oil gets hot, cook chicharo, bell peppe and onion for 5 minutes. Then transfer in a plate. Set aside.
In the same pan, add more cooking oil and stir-fry the pork for 10 minutes or until crispy brown.
Then, transfer to a serving plate. Serve and enjoy!
