These are a tasty substitute for bruschetta for a grain free diet especially. They make nice appetizers as well if cut into individual squares.
Zucchini squash sliced thinly
Extra virgin olive oil
tomato sauce or non- tomato sauce (see recipe for non-tomato sauce found here http://nannykimsrecipes.blogspot.com/2016/07/non-spaghetti-sauce.html)
black olives (or olives of choice)
Preheat oven to Broil. Place sliced zucchini on oiled cookie sheet (I used non-stick). Brush with olive oil. Sprinkle with seasoning. Let cook under broiler until edges just start to brown and zucchini is tender (or however you like it). Remove from oven and spread with desired toppings.
