Toast the Pecans: Place the raw pecan halves in a small, dry skillet over medium-low heat. Toast for 3–4 minutes, shaking the pan occasionally, until they become fragrant and deepen slightly in color. Remove from heat and set aside to cool.
Prepare the Berries: While the nuts toast, gently rinse the blueberries and raspberries under cool water. Pat them completely dry with a paper towel and set aside.
Infuse the Yogurt: In a separate mixing bowl, combine the plain Greek yogurt and the ground cardamom. Whisk until the spice is fully incorporated and the yogurt is smooth and creamy.
Build the Base: Divide the cardamom-infused yogurt evenly among the three wide, shallow bowls, creating a smooth foundation for the toppings.
Add the Crunch: Coarsely chop the cooled, toasted pecans. Sprinkle the chopped pecans and the low-sodium granola over the surface of the yogurt in each bowl.
Garnish with Fruit: Artfully arrange the fresh blueberries and raspberries over the layer of granola and nuts.
Final Drizzle: Finish each bowl with a light drizzle of agave nectar. Serve immediately to enjoy the contrast of creamy, crunchy, and fresh textures.
