Ingredients
  

Ingredients
  • 8 oz whole wheat egg noodles
  • 2 cans (5 oz each) tuna in water, drained
  • 1 cup plain Greek yogurt
  • 1 cup low-fat milk
  • 1 cup frozen peas
  • 1 medium onion, diced
  • 2 celery stalks, chopped
  • 2 cloves garlic, minced
  • 1 cup reduced-fat cheddar cheese, shredded
  • 1/4 cup whole wheat breadcrumbs
  • 1 tablespoon olive oil
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon paprika
  • Salt and pepper to taste
  • Fresh parsley for garnish

Method
 

Instructions
  1. Cook the whole wheat egg noodles according to package directions until al dente. Drain well and set aside. While the noodles cook, preheat your oven to 375°F (190°C).
  2. Heat olive oil in a large skillet over medium heat. Add diced onion and chopped celery, cooking until softened, about 5 minutes. Add minced garlic and cook for another minute until fragrant.
  3. Reduce heat to low and stir in Greek yogurt, low-fat milk, and Dijon mustard. Whisk until smooth and heated through. Be careful not to boil the sauce as this can cause the yogurt to separate.
  4. In a large mixing bowl, combine the cooked noodles, tuna, frozen peas, and the creamy sauce mixture. Gently fold in half of the shredded cheese. Season with salt, pepper, and paprika.
  5. Transfer the mixture to a greased 9x13 inch baking dish. Top with remaining cheese and breadcrumbs. Bake for 20-25 minutes until bubbly and golden brown on top. For extra crispiness, broil for the last 2-3 minutes.
  6. Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley and enjoy this lighter take on a classic comfort food favorite.

Notes

Choose tuna packed in water rather than oil to keep the dish lean. Cook noodles al dente since they'll continue cooking in the oven. Casserole can be assembled up to a day in advance and refrigerated.
