Preheat oven to 400 degrees and line a baking sheet with either parchment paper or a silicone liner. Set aside.

Wash your cauliflower and cut in half (or use the whole thing, depending on how much you want). Slice into 1″ thick pieces or separate into florets, however you prefer. Arrange onto your baking sheet

Brush each piece of cauliflower with olive oil then sprinkle with salt, pepper, and ground cumin. Flip the pieces over and do the same to the other side. Squeeze some lemon over the pieces for added flavor.

Cook for 10 minutes, flip all the pieces, then cook another 10 minutes until they start to brown.
