The genius idea here is pulsing sliced pepperoni with bread crumbs to add a ton of extra flavor and a great crunch to broccoli. Slideshow: Great Roasted Vegetable Recipes
Preheat the oven to 425°. In a mini food processor, pulse the pepperoni with the garlic until finely chopped. Add the panko and pulse just to combine.
In a medium skillet, heat 2 tablespoons of the olive oil. Add the crumb mixture and cook over moderate heat, stirring, until crisp and golden, about 5 minutes. Scrape onto a plate and let cool.
Meanwhile, in a bowl, toss the broccoli with the remaining 1/4 cup of olive oil and season with salt. Spread the broccoli on a baking sheet and roast for about 15 minutes, turning once, until tender and browned in spots. Spread the mustard on one side of the broccoli and press the broccoli into the crumbs. Transfer the broccoli to a platter, sprinkle with any remaining crumbs and serve.
This was so good! We used turkey pepperoni for a little healthier version. I will definitely make this again!
