Preheat oven to 425 degrees and line a baking sheet with parchment. Place the cauliflower in a food processor. Process the cauliflower on low until it become fine and crumbly resembling rice. Heat a nonstick skillet over medium heat and add the cauliflower rice to the pan. Cook the cauliflower, stirring frequently, until it becomes dry and most of the moisture has cooked out. Allow to cool to room temperature in the pan. Transfer the cauliflower to a large bowl. Add the eggs, 1 cup shredded Italian Blend cheese, Italian seasoning, 1 tablespoon basil, garlic powder, salt and pepper to the bowl. Using your hands or a wooden spoon, stir until thoroughly combined. Turn the cauliflower mixture out onto the parchment lined baking sheet and pat into a rectangle approximately 1/2 inch thick. Transfer the baking sheet to the oven and bake for 12 to 14 minutes, or until golden brown and dry around the edges. Top with the remaining Italian blend cheese and the cheddar cheese over the breadsticks. Continue baking for an additional 2 to 3 minutes or until the cheese is bubbling and golden. Sprinkle the remaining basil over the breadsticks and cut into 1 1/2 inch wide strips. Serve immediately.
