Preheat oven to 325 degrees F (160 degrees C).
Mix the Old Fashioned Rolled Oats (1 1/2 cup), Walnut (1 cup), Sesame Seeds (1 tablespoon), Coconut Oil (5 tablespoon), Honey (1/4 cup), Vanilla Extract (1 teaspoon), and Ground Cinnamon (1/2 teaspoon) together in a bowl until thoroughly coated.
Press about 3 tablespoons of the mixture into 8 greased mini tart pans. Use the back of an oiled spoon to help press the granola evenly across the pan and up the sides.
Bake in the center rack of the oven for about 15 to 17 minutes, or until golden. Immediately after you remove the tart shells from the oven, use the back of the spoon to press down the centers of the crust to create more of an indentation, and push up the sides.
Allow to cool completely in the pan before removing. Use a small knife to gently release the sides of the crust, working around each side, then very carefully remove it from the pan, turning over if needed into your hand. The crust should be crisp on the sides and hold together.
Fill each tart with 3 to 4 tablespoon Greek Yogurt (2 cup), smooth out evenly. Arrange the Fresh Strawberry (1 cup), Fresh Raspberries (1 cup), Fresh Blueberries (1 cup), and Green Apple (1 cup) on top and serve immediately. The crust will become a little soggy if left to sit for too long. Serve and enjoy!
