This is so simple and delicious!  Take a whole head of cauliflower and slice rounds as flat as possible.  Some will fall off in small pieces, use this too as it all tastes good.  Place on a parchment lined cookie sheet and drizzle with olive oil.  Bake at 400 degrees until cauliflower is crisp and slightly browned on edges (You should turn vegetables to cook evenly.).  When done add ¼ cup of freshly chopped chives, 1 tablespoon of chopped thyme, kosher salt to taste, and ½ cup of grated sharp cheddar cheese.  Put in oven for 2-3 minutes more and serve.  This is an excellent easy side dish.  Enjoy!
