Heat a grill to medium high. Remove the green outer leaves from a head of cauliflower. Cut two - 1 inch steaks from the center of the head, through the stem, being sure to leave the stem intact.

Trim the rounded outer edges from the remaining ends and use a skewer to thread though the thicker pieces, creating a (pieced together) steak. Repeat with remaining piece.

Whisk together the lemon zest, juice, garlic powder, red pepper flakes, salt, pepper, herbs and oil.

Lay the steaks on a sheet or plate and brush lightly with 1 Tbsp olive oil. Season lightly with salt and pepper.

Flip the steaks and spread one half of the marinade over the steaks and season with salt and pepper.

Grill covered, marinade side up, for 2-3 mins. Carefully flip and distribute the remaining marinade over the steaks. Cover and cook an additional 2-3 mins. The skewered steaks may fall apart slightly, but no worries, just carefully turn so all of the pieces cook evenly.

Sprinkle with parmesan and close the grill and cook 1-2 mins.

Remove and serve with herbs and parmesan if desired.
