Vegetarian Broccoli-Cheese Pie

Preheat oven to 350 degrees F. Coat a 9-inch deep-dish pie pan (6-cup capacity) with cooking spray. Add breadcrumbs, tilting to coat bottom and sides.

Whisk eggs, milk, hot sauce, salt and pepper in a large bowl. Add bread and stir to coat. Set aside in the refrigerator.

Steam broccoli until just tender, 3 to 4 minutes. Refresh under cold water and drain well. Chop coarsely.

Heat oil in a medium nonstick skillet over medium-high heat. Add onion; cook, stirring often, until softened and light golden, 3 to 5 minutes. Add the onion mixture and broccoli to the egg mixture; stir in cheese. Pour into the prepared pan, spreading evenly.

Bake the pie until light golden and set, 45 to 50 minutes. Let cool slightly, cut into wedges and serve.
