Preheat the oven to 425°F. Line a baking sheet with parchment paper.
Pound the chicken breast slightly to an even thickness. Season both sides with salt, pepper, and garlic powder.
In a shallow bowl, whisk the egg white. In another bowl, place the panko bread crumbs.
Dip the chicken in the egg white, ensuring it’s well-coated, then dredge in panko until fully covered.
Place the chicken on the baking sheet and bake for 18-20 minutes, flipping halfway through, until the chicken is cooked and the coating is crispy.
While the chicken bakes, combine honey, rice vinegar, and water in a small saucepan over low heat to create a light sweet and sour glaze. Simmer for 3-4 minutes and set aside.
Thinly slice the red bell pepper and arrange on another tray. Roast in the oven for about 10 minutes or until tender and slightly charred.
Plate the crispy chicken, top with the roasted bell peppers and pineapple chunks, and drizzle with the sweet and sour glaze.
Serve immediately and enjoy your balanced, flavorful meal.
