Preheat oven to 400 degrees. Trim and wash cauliflower and cut into bit sized florets.
Place cauliflower in bowl and toss with oil. Sprinkle nutritional yeast on top and toss until cauliflower is evenly coated.
Spread cauliflower evenly in parchment lined pan and sprinkle with sea salt and pepper.
Roast in oven for 45 minutes or until slightly browned and tender. Serve immediately and enjoy!
If you're not too heavy handed with the oil, these florets keep well in the fridge and can be included on top of your lunch salad the next day.
