Sweet and Sour Pork

I love any stir fry dishes that's sweet 'n' sour, be it with fried fish or pork, it literally gets me salivating, haha. So tonight, I thought I make this sweet and sour pork for my family (and myself, heehee).

Ingredients:
300g of tenderloin pork, cut to bite size
a small can of cube pineapple
1 red bell pepper, cut to bite size
1 small zucchini, peeled and cut to bite size
1 small red onion, peeled and cut to bite size
3 cloves of garlic, minced

Seasoning A:
1/4 ground pepper
1/2 tsp soy sauce
1/4 sesame oil
1 tsp mirin (Japanese cooking wine)
2 tbsp cornflour

Seasoning B:
4 tbsp ketchup
Juice form the can pineapple
1 tbsp sugar
1 tsp oyster sauce
1/4 tsp salt
1 tsp cornflour dissolved in 1 tbsp water

Method:

1. Marinate the pork with Seasoning A and set aside for at least 15 minutes.
2. Heat up enough oil to fry the marinated pork, until cooked and golden brown. Set aside.
   
3. Heat up a little oil, stir fry garlic for a minute, add red onion, bell pepper and zucchini, cook for 2 to 3 minutes. Add pineapple and seasoning B, stir and cover for 1 minute.
4. Add pork and stir fry for 30 seconds and dish up to serve while hot.
