I start by cutting the chicken into bite-sized pieces so they cook evenly. Then I season them lightly with salt and pepper, which helps boost the flavor before the coating step.
Next, I dip each piece first in the beaten eggs, then in cornstarch. This double layer is key for that crispy, golden exterior. I make sure each piece is evenly coated without clumps.
I arrange the coated chicken on a parchment-lined baking sheet. A quick drizzle of vegetable oil ensures the pieces crisp up in the oven. Then I bake until golden and cooked through, usually around 20-25 minutes.
While the chicken bakes, I chop the bell pepper and onion, and drain the pineapple chunks. I sauté them lightly if I want extra softness, or leave them raw for a fresh crunch.
I whisk together sweet and sour sauce ingredients in a small bowl. If I make my own, I combine vinegar, ketchup, brown sugar, and a touch of soy sauce. Heating it slightly helps it coat the chicken better.
Once the chicken is done, I toss it gently with the veggies, pineapple, and sauce. The key is to coat everything evenly without breaking the chicken apart. Serve immediately for best taste.
