Start by boiling a large pot of water. Once it’s bubbling, add the whole wheat macaroni.
Cook the macaroni for about 8 minutes or until it’s al dente.
While the macaroni is cooking, heat the butter in another pan.
Add the cooked and chopped chicken breast to the pan and sauté for a few minutes.
In a bowl, mix the Greek yogurt, milk, salt, and pepper to make a smooth sauce.
Once the macaroni is ready, drain it and return to the pot.
Pour the Greek yogurt mixture over the macaroni and mix well.
Add the shredded cheddar cheese to the mix, ensuring every piece of macaroni is well-coated.
Transfer the cheesy macaroni into a baking dish.
In a separate bowl, combine the bread crumbs with the olive oil.
Sprinkle the breadcrumb mixture over the mac n cheese.
Bake in a preheated oven at 375°F (190°C) for 15 minutes or until the top is golden brown.
