Spinach-Cheese Bagel Bites

Preheat oven to 375 °F (190°C). Split bagels in half horizontally. With a grapefruit spoon, hollow out some of the bread*. Place spinach in microwaveable bowl; sprinkle lightly with water. Cover loosely and microwave on high until spinach is wilted, about 1 minute, 20 seconds. Remove and drain well. Combine spinach, cheeses and remaining ingredients, except bagels. Place bagel shells on foil-lined baking sheet. Place about 1/4 cup cheese mixture on each bagel. Bake bagel until cheese has melted and edges are lightly toasted, about 8 to 10 minutes. Cut each bagel half into quarters to make a total of 32 pieces.
