Pre-heat oven to 350°F and line an 8 x 8-inch baking pan with a piece of parchment paper. Leave a bit of overlap on the sides of the pan.
In a high-powered blender or a food processor, combine the pitted dates, protein powder, almond butter, honey, coconut oil, and vanilla extract. Blend until the mixture is smooth and creamy.
Transfer the date mixture into a large mixing bowl and add the cinnamon, salt, sunflower seeds, oats, and almonds.
Mix until well combined and the oats and nuts are nicely coated.
Transfer the granola mixture to the prepared baking dish and pat down into an even layer. Place in the pre-heated oven and bake until lightly golden brown and toasted on top, approximately 20 minutes.
Remove from oven and cool to room temperature. Granola will crumble as you remove it from the pan, with some larger chunks.
To serve in parfait, alternate layers of Greek yogurt, crunchy granola, sliced bananas, and fresh strawberries in 4 parfait dishes or mason jars. Enjoy!
