Preheat your oven to 375°F (190°C).
In a small skillet over medium heat, sauté the baby spinach and minced garlic until the spinach is fully wilted and the garlic is fragrant.
In a medium mixing bowl, combine the cooked shredded chicken breast, nonfat Greek yogurt, chopped artichoke hearts, parmesan cheese, lemon juice, sea salt, and black pepper.
Stir the sautéed spinach and garlic into the chicken mixture until well incorporated.
Transfer the mixture into a small oven-safe baking dish or ramekin, smoothing the top with a spoon.
Evenly sprinkle the shredded mozzarella cheese over the top of the mixture.
Place in the oven and bake for 15 to 20 minutes, or until the dip is heated through and the cheese is golden and bubbling.
While the dip bakes, toast the slice of sprouted grain bread until crisp.
Remove the dip from the oven and serve immediately alongside the warm toasted bread.
