Heat your grill on high for at least 15 minutes.
Add spinach to a colander and press out as much water as possible. Add all pesto ingredients to a high speed blender and blend until smooth. If the blender isn’t blending, add water, 1 tablespoon at a time, until it blends. I like the pesto to be slightly chunky with crunchy almonds!

In a large bowl, add the chicken, 1 cup pesto, ½ cup mozzarella, remaining ½ teaspoon salt, and ½ teaspoon black pepper. Divide between the zucchini, stuffing it into the scooped out center. Top with marinara, and remaining ½ cup mozzarella cheese.
Turn the grill down to medium and carefully place each zucchini back onto the grill and cook, covered, for 4-6 more minutes, or until the zucchini is tender and cheese is melted.Serve topped with black pepper and devour!
