Preheat your oven to 375°F (190°C). Lightly grease a large baking dish with vegetable oil.
In the baking dish, mix together the mushroom soup, Greek yogurt, vegetable broth, minced garlic, Italian seasoning, salt, and pepper.
Add in the kale, orzo pasta, diced chicken, and half of the Cheddar cheese (2.5 cups), stirring until everything is mixed through.
Cover with the remaining Cheddar cheese (2.5 cups) evenly across the top.
Sprinkle the crunchy breadcrumb topping across the cheese layer.
Cover the dish with aluminum foil and bake for 20 minutes.
Remove the foil and bake for an additional 15 minutes or until the top is golden and the mixture is bubbly. Let stand for 5 minutes before serving.
Notes
To make your own Italian seasoning, combine 2 teaspoons dried basil, 1 teaspoon dried oregano, 1 teaspoon dried rosemary, 1 teaspoon dried thyme, 1 teaspoon garlic powder. For a more cheesy dish, you can add more Cheddar on top.
