For the Sweet and Sour Sauce:
Season chicken pieces with salt and pepper.
Dredge in cornstarch, then dip into beaten eggs, follow with seasoned flour.
Heat oil in a pan over medium-high.
Fry chicken in batches until crispy and golden. Drain on paper towels.
Make the Sauce:
In a small pot, mix sugar, ketchup, vinegar, soy sauce, and garlic powder.
Bring to a simmer. Stir in the cornstarch slurry and cook until thickened.
In a clean pan, lightly stir-fry peppers, onions, and pineapple. Add the fried chicken back into the pan.
Pour the sweet and sour sauce over the chicken and veggies. Toss quickly to coat everything evenly.
Serve hot over white rice or fried rice. Garnish with sesame seeds or green onions if you want.
