Coat the cauliflower slices with olive oil, sea salt, freshly cracked black pepper, and crushed red pepper flakes, to taste.
Gently toss to coat evenly. Spread the cauliflower out over the baking sheet along with the garlic cloves (with the skin still on).
Roast in the oven for 10-12 minutes, or until golden brown.
Carefully flip the cauliflower pieces over and continue to roast for another 5-7 minutes, or until golden brown and tender.
Remove from the oven. Take the cloves of garlic off the baking sheet and allow to cool for a minute before removing the skins.
Slice the garlic and sprinkle on top of the cauliflower. Add the toasted pine nuts and fresh parsley. Squeeze fresh lemon juice on top, to taste, and serve immediately. Enjoy.
