Preheat oven to 425 degrees. Wash cauliflower, and cut up into big bite size pieces. Place cauliflower florets on cookie sheet. Drizzle olive oil all over them. Just a little goes a long way. Sprinkle paprika, salt, pepper and lemon juice all over it. Mix it all up with your clean hands until the florets are covered with paprika color. Bake for 30-35 minutes. Enjoy!
