Zucchini Crust with Tuna Salad Topping

For the crust: Combine the 2 grated zucchinis, 1/2 onion, 1 carrot, 1 egg, 1 egg white, 1/2 cup whole wheat flour, 1/2 cup shredded part-skim mozzarella, 1/2 tsp baking powder, and garlic powder in a bowl. Mix thoroughly. Press the mixture onto a baking sheet to form a crust. Bake at 400°F (200°C) for approximately 25 minutes, or until golden and set. 

For the topping: Prepare tuna salad by mixing tuna (canned, drained - implied) with Greek yogurt or mayonnaise, mustard, salt, and garlic powder to taste. 

Once the crust is baked and slightly cooled, top it generously with the prepared tuna salad. Serve immediately. Delicious!
