Add the tomatoes, cucumber, olives, onion and cheese in a large bowl and toss to combine
Heat your waffle iron and coat it with non-stick cooking spray. Place one biscuit at a time in the waffle iron (if it is a large enough waffle iron, you can do more than one at a time). Close the iron and cook for about 2 minutes, or until the biscuit is golden brown.
Spread some of the hummus on each waffle and top with the Greek salsa mixture. Enjoy!
*Feel free to switch up the flavor of hummus to whatever your favorite flavor is!
