Season the white cauliflower with turmeric, smoked paprika, salt, and pepper. Then season the purple cauliflower and broccoli with salt and pepper. Add garlic granules or powder if you like.
Drizzle with olive oil, and mix everything together (mix the white cauliflower with turmeric separately). Lay on a sheet pan, and roast for 20-30 minutes at 180°C (356°F) or until the veggies are soft and cooked through.
Lemon garlic salad dressing
Start by finely chopping fresh parsley leaves. Add minced garlic, mustard, olive oil, lemon juice, maple syrup or honey, salt and pepper. Whisk everything together until well combined.
Pour the dressing over the roasted cauliflower and broccoli, give the salad a good mix then finish with flaked almond and serve.
Notes
Feel free to season all of the veggies with one seasoning which is the turmeric and smoked paprika, but this might change the vibrant purple color as well as the green color of broccoli.
Garnish the salad with flaked almonds, or sunflower seeds.
For an easy salad dressing, just drizzle some extra virgin olive oil and lemon juice over the salad, and season with salt and pepper.
This recipe works for any kind of cauliflower, not necessarily just purple cauliflower.
