Sweet and Sour Pork

My first attempt to make a sweet and sour pork. Hubby and Jake prefers chicken so I ended up eating all of this after hubby digged and gobbled all the pork.
My sister forwarded this recipe through email a long time ago. All you need is;

1/2 kl pork loin
1 small can pineapple chunks
1 large onion, quartered
1 red & 1 green bell peppers, sliced into strips. ( I didn't have green bell peppers, I used what's in our fridge)
2 tbsp of soy sauce
3 tbsp of peanut oil
4 tbs of cornstarch 3 tbsp sugar 1 tsp salt 3 cloves minced garlic
3 tbsp ketchup

~ In a pot, boil pork in 2 cups of water with 1/2 tsp. of salt until tender, then drain(keep the pork stock for later)
~ Mix 2 tbsp of cornstarch and soy sauce then coat the pork with cornstarch mixture.
~ Fry the pork in a skillet until golden brown, set aside
~ Dissolve the remaining 2 tbsp of cornstarch on 1/2 cup of pork stock -set aside
~ Saute garlic and onions on oil,then add the bell peppers, pineapple chunks(including the syrup), ketchup, sugar, 1/2 tsp salt and dissolved cornstarch. Stir until sauce thickens.
~ Pour over fried pork then serve with rice.
