1. To begin, pulse the broccoli florets in a food processor until they form rice-sized pieces. Heat olive oil in a pan over medium heat and sauté the garlic for about 1 minute. Add the broccoli rice, season with salt and pepper, and cook for 5 minutes until tender. Stir in Parmesan cheese if desired.

2. Heat olive oil in a large skillet over medium-high heat. Add the shrimp, season with salt and pepper, and cook for 1-2 minutes per side until pink. Reduce heat to medium-low, add butter, garlic, and red pepper flakes. Stir until butter melts and garlic infuses the shrimp. Cook for an additional 2-3 minutes. Finish with lemon juice if desired.

3. To serve, place broccoli rice on a plate and top with shrimp, spooning any remaining butter sauce over the top. Garnish with parsley.
