BAKE in top third of oven until tops are crispy and browned, about 20 min. Flip bacon bites and bake 5 more min. Remove from oven and lightly dab with paper towels. Set aside to cool slightly.
COMBINE water with sugar, vinegar, chili-garlic sauce, cornstarch and ginger in a small saucepan and set over medium-high. Bring to a boil, then reduce heat to medium-low. Simmer until sauce has thickened slightly, about 5 min. Transfer sauce to a small bowl. Serve with warm bacon bites.
