Mix flour, salt, and pepper together in a big bowl or bag. Toss in the chunks of chicken until coated.
Heat a large skillet to medium heat. Add the olive oil, then fry the chicken flipping after 3-5 minutes. Add the cloves of garlic and cook for another 5 minutes. Be sure the chicken is fully cooked - no traces of pink should be left. Turn the heat down to low.
Add the sweet and sour sauce to the frying pan with the chicken. Turn the heat back up to medium.
Let this mixture begin to bubble, then turn down the heat to low (for about 3 minutes).
Add the green onions and serve over long-grain jasmine rice.
