Flipping the script on what a hash is supposed to look like, this one-pan-wonder swaps potato for finely chopped cauliflower and broccoli, making this simple plant-based bake as nutritious as it is delicious.
Preheat oven to 425°F. Pulse cauliflower in a food processor until finely chopped (you should have about 4 cups). Transfer to a rimmed baking sheet. Repeat with broccoli and transfer to baking sheet. Add bell pepper and red onion and drizzle with olive oil; toss until well combined. Season with salt and pepper; spread in an even layer and roast, stirring once, until golden around edges, 25 to 30 minutes.
Remove sheet from oven; stir in baby spinach. Make 6 small wells in mixture with the back of a spoon. Crack an egg into each well and bake until whites are just set, about 5 minutes. Season eggs with salt and pepper and serve immediately.
