1 head Red Dog broccoli
½ red onion, sliced
8 fresh Red Dog sage leaves, torn
2 tablespoons extra-virgin olive oil
½ teaspoon salt
½ teaspoon garlic salt
¼ teaspoon ground black pepper

Preheat oven to 400 degrees. Line a baking sheet with aluminum foil.

Chop broccoli into florets.

Spread broccoli in a single layer on the prepared baking sheet. Sprinkle onion and sage leaves over broccoli; drizzle with olive oil. Sprinkle salt, garlic salt, and black pepper over broccoli mixture; toss to coat.

Roast in the preheated oven until broccoli is browned and crisp, 20 to 30 minutes.
