Step 1

Mix all the ingredients for the sauce in a large bowl or measuring cup. Mix until the cornstarch is dissolved. Set aside.

Step 2

Heat a pan or wok over medium high heat. Add 1-2 tbsp neutral oil.

Step 3

Once hot, stir-fry the onion, carrot, and bell peppers for 2-3 minutes until the carrots are tender.

Step 4

Add in the pineapple chunks and cook for 1 minutes

Step 5

Lower the heat to medium. Give the sauce a good mix again since the starch tends to sit at the bottom.

Step 6

Over medium heat, pour in the sauce to the pan.

Step 7

Mix well and then leave the sauce to boil for 2 to 3 minutes. Continuously mix until the sauce thickens.

Step 8

Once the sauce has thickened, add in the bola-bola or meat balls and immediately mix well in the sauce. Leave the meatballs to simmer in the sauce for 2-3 minutes.

Step 9

Turn off the heat then serve the sweet and sour bola-bola or meatballs immediately. Enjoy this while hot with some steamed rice.
