Preheat the oven to 220 Degrees Celsius.
Place broccoli florets into a food processor and blitz until fine. Pop into a heatproof bowl, cover with clingfilm and microwave for 8 - 10 minutes.
Meanwhile, fry the bacon ( I don't use oil when frying bacon) until crispy and place on paper towel to absorb residual oil from bacon fat.
Carefully remove cling film. Mix the base in ingredients vigorously into the steamed broccoli until well combined.
Press mixture onto a baking paper lined baking tray. Bake for 10 minutes.
Remove from the oven and top with bacon, brie and cranberries. Drizzle lightly with olive oil and season with salt and pepper.
Bake for another 8 - 10 minutes or until golden.
Top with rocket and serve immediately!
