Piri-piri cauliflower with lemon-parsley cous cous

I have an abundance of parsley. When I say an abundance, I could literally have picked about 80 bunches this size! I am planning to freeze alot for use within the winter months, but I thought it was time to start adding large quantities to most meals for the next month! I had planned to serve this with halloumi, but I forgot to get it out of the freezer!
