Step 1: Cook the Pasta

1. Bring a large pot of salted water to a boil.
2. Add egg noodles and cook until just al dente (about 1-2 minutes less than package instructions).
3. Drain and set aside.

Step 2: Prepare the Sauce

1. In a large mixing bowl, whisk together:
   • Cream of mushroom soup
   • Milk
   • Salt, pepper, garlic powder, and onion powder
2. Stir in cheddar cheese until well combined.

Step 3: Assemble the Casserole

1. Preheat the oven to 375°F (190°C).
2. In the casserole dish, combine:
   • Cooked pasta
   • Drained tuna
   • Frozen peas (if using)
   • Creamy sauce mixture
3. Stir until everything is evenly coated.

Step 4: Add the Topping

1. In a small bowl, mix breadcrumbs (or crushed chips) with melted butter.
2. Sprinkle evenly over the top of the casserole.
3. (Optional) Add extra cheese for a gooey, golden-brown topping.

Step 5: Bake

1. Place the casserole in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and the sauce is bubbling.

Step 6: Rest and Serve

1. Let the casserole rest for 5-10 minutes before serving.
2. Garnish with fresh parsley or extra cheese, if desired.
