Instructions
Preheat oven to 350 degrees.
Lightly grease a deep casserole dish with non-stick cooking spray. Set aside.
In a large, heavy-bottomed pot, melt the butter over medium heat. Add the onions, salt, and ground black pepper. Cook the onions until well done - about 7-8 minutes.
Sprinkle in the flour and stir into the butter and onion mixture. Cook for 2-3 minutes.
Next, whisk in the milk. Continue to cook and whisk over medium heat. The milk will thicken. This will take about 5 minutes.
Add the grated cheese and turn off the heat. Stir in the cheese until melted completely. Set aside.
Add the cooked pasta, corn, peas, and parsley to the cheese sauce. Stir well to combine.
Add in the tuna. Stir into the pasta mixture, but not too much. Try to keep the tuna pieces from breaking up too much.
Poor the entire mixture into the prepared casserole dish.
Top with panko and bake covered for 20 minutes. Uncover and bake for 20 additional minutes.
