Step 1

Preheat oven to 375°F. Heat oil in a medium saucepan over medium-high.

Step 2

Add ginger, garlic, and jalapeño; cook, stirring often, until fragrant, about 1 minute. Add onion and salt, and cook, stirring often, until onion begins to soften, about 2 minutes. Add brown sugar, soy sauce, ketchup, and rice vinegar; bring to a simmer, stirring constantly, until sugar is dissolved.

Step 3

Sprinkle pineapple and bell pepper evenly in bottom of a lightly greased 3 quart baking dish. Pour brown sugar-soy mixture over pineapple mixture; top evenly with chicken tenders.

Step 4

Bake in preheated oven until bubbly, and chicken is slightly crisp on top, about 20 minutes.

Step 5

Toss mixture lightly to coat chicken, and sprinkle with scallions. Serve over rice.
