- Saute onions and garlic with olive oil until onions are translucent/ cooked.  Mix in pepper flakes and oregano.  Continue mixing for one minute avoiding any burns.   
- Add prawn and splash in the table wine.  I use any leftover old wine for this purposes.  Cook prawn and scoop it out when cook.  Set it aside.   
- On the same pan, add feta crumbles.  Mix well over medium heat.  Add tomatoes and let it cook for five minutes.  Add the heavy cream and cook for another five minutes. 
- Blend in the penne pasta to the sauce and add the butter, mushroom, zuccini and spinach. Mix carefully and cook until vegetables are done.   
- Mix in cooked prawn and dash with salt and pepper to desired taste. 
- Garnish with parmesan  cheese and enjoy.
